...Pin curls have been around for decades, and for good reason. The technique is full-proof, which is why professional hairstylists and celebrities continue to use it. Keep reading to learn how to create glamorous, silky curls in a matter of minutes. The best way to start this look is with clean hair. Wash hair with your normal shampoo and conditioner, and then towel dry until it is only semi-damp. Apply a frizz-fighting crème, and proceed to blow dry hair straight. Gather the essential pin-curl materials: setting lotion, bobby pins and a rat tail comb. Make sure that you place your pins in an easily accessible place, preferably in front of a mirror. Begin by applying a bit of setting lotion to a one-inch section of hair; this will make strands malleable, and more likely to hold a curl. Wrap the ends of the hair around two fingers, circling twice. Proceed to roll the hair up towards the scalp in a tight loop. Be sure to loop the hair in a circle without actually twisting the hair itself, as twisting the strands can affect the integrity of the curl. Once you have rolled the hair all the way up to the scalp, gently secure the curl with two bobby pins, crossing over the loop of hair in an “x” pattern. Repeat the process until you have pinned the entire head of hair. Wrap a silk scarf around your head and apply gentle heat to the hair, using a blow dryer on the lowest setting. Remove the scarf and allow hair to cool. Gently remove the bobby pins to reveal a head...

...Museum Paper In this week’s class, we all made a visit to San Francisco Museum of Modern Art. Actually, this was my first time to take a tour to a museum in U.S. Museum is a place worth visiting, and it really was a better experience for me. I saw so many artworks in this big museum. Now, I select three of these artworks to share with you. They completely shocked me and gave a deep expression at first sight. First of all, I want to show my favorite one to you. It is called “bridge”, and it was painted by Joseph Stella. He was an American but born in Italy, Stella immigrated to the United States at the age of eighteen, and his paintings always express the shock and admiration he felt as a European who came to Manhattan from an older, more traditional culture. Stella moved to Brooklyn in 1916, and crossed this bridge regularly. He did several paintings of the bridge, all from the same viewpoint. His perspective captures the impression you get when you walk over the bridge. In my opinion, Bridge combines Futurist elements with American subjects, and it was showed me strong technology and modern feeling. From the brief introduction of this artwork, I also saw Joseph Stella's own words about the bridge: "Seen for the first time, as a weird metallic Apparition under a metallic sky…supported by the massive dark towers dominating the surrounding tumult of the surging skyscrapers with their gothic majesty sealed in the purity of their arches, the cables, like divine messages from above...

...deeds. The main factor of the poor and homelessness is starvation, the need for food is harming the poor’s health and days of life. So, the first thing I would draw would be multiple factories that produce unlimited amount of free artificial and organic food for the dirt poor to aid them in their needs. The poverty in our world is outrageous and in danger of needing help. In my kindness I’d also love to help them by supplying them a home. A creation of multiple apartments in countries who need them the most like Ghana, Nigeria and others located in Africa would be fascinating. Helping others composes my feelings into feeling courteous and grateful for what I accomplish. No better feeling than knowing you rescued multiple human lives. Drawing everything I “want” and do not need is being selfish if I am already living a good healthy life. When you have the power of creating whatever you want you have to cautious and careful into choosing what to draw. The capability of the magic purple crayon is deadly and you should use it...

...You have 8 steps to drawing a single color illustration. Can you simply explain them? [Rough sketch] For a single illustration, the composition is very important. I have to think about what kind of illustration I want, and what kind of message I want to convey. Because it's only a single illustration, from there the viewer will imagine what kind of scene or story is taking place, so I have to consider the composition and the characters' expressions. (For example, "These two are in the helicopter's searchlight and are being chased across the rooftops...!" or "These two are heading to a formal party♪ They'll be drinking champagne♪") There have been plenty of times when it took me several days to draw countless rough sketches until I made one that I liked (^^; If I don't decide the lines for inking during the rough sketch stage, I'll mess up later on. [Underdrawing] Once I've decided on the rough sketch, I take the paper that I'll do the coloring on and attach the rough sketch underneath, then use a light table to reproduce the drawing. However, even if I trace the illuminated image, I'll never get exactly the same drawing... The characters' expressions that I've spent so much time deciding on will end up changing a little at this stage, so I make some minute adjustments while taking care to not damage the paper. The paper I use is gentle and becomes fuzzy easily, so I have to be very mindful. That's because when you apply color ink to a damaged part, it...

...many artists that are well known to us these days even though they died many years ago, e.g. Pablo Picasso, Leonardo da Vinci, and Van Gogh. They became famous because of there high quality work that gave an affect on people when they saw the painting. In my opinion not all paintings are thought to be art because some of them do not make sense. Maybe the person who drew it understands what it meant but for me I don’t understand it. The painter should be straight forward when trying to tell the audience something in his painting. Putting many different pictures or shapes in a painting in a weird way makes the quality of it very low without any form of organization. A person before painting should organize his/her thoughts at first so when drawing he/she will have a goal that he/she want to show. The image above is one of my favorite paintings. It is called Leaf Album and it was painted by Chen Hongshou. I liked because it gave me the sense of sympathy and harmony. The colors of it are very soft and...

...Lab Assignment Part A – Analysis of Literature Data 1. Proof Stress vs Cold Work 600 500 Proof stress (MPa) 400 15µm 300 200 100 0 0 10 20 30 40 50 60 70 Cold work (%) 70µm Sample 5 - 15µm Sample 5 - 70µm Figure 1 – Proof Stress vs Cold Work of 70/30 Brass As can be seen from Figure 1, the 0% cold worked points (Sample 5) for each grain size is in line with the curve of the other four points. The amount of proof stress increases with increased cold work, but approaches an asymptote at a point of maximum increase in proof stress. Cold working uses processes such as drawings to deform the grains in a material, thereby increasing the proof stress of the material. 2. (i) Grain size strengthening is a process that reduces the sizes of the grains in a material, typically by annealing. This works to increase the strength of the material through the fact that grain boundaries act as a barrier to dislocations. As can be seen in Figure 1, decrease in grain size causes an increase in proof stress. Cold working involves plastically deforming a material such that dislocations become concentrated. These dislocations then become entangled, hindering further dislocation movement, thereby increasing the strength of the material. As can be seen in Figure 1, proof stress can be increased dramatically by cold work hardening, but only to a point. (ii) Grain size strengthening and cold work hardening can be used together to form a much stronger material. Grain size strengthening reduces...

...astronaut, a teacher, a race-car driver, a tattoo artist, a janitor. What would I be? I felt as though my days of playing in the sandbox and eating glue were over - I had to plan my future. But there, face to face with my teacher, I declared, "A giraffe!" My teacher stared at me for a long time; I still wonder what was going through her head. Maybe she thought I was on special medication or my parents were free-spirited hippies who taught me I could be whoever (or whatever) I wanted. Then she just smiled and turned back to the class. "Children, next Friday is 'Bring Your Kids to Work Day.' All of you will join one of your parents at his or her job and learn about what they do for a living. And on Monday, you'll share that by drawing a picture about your day! Won't that be exciting?" She clasped her hands and grinned at the rugrats sitting below her. Just then her eyes focused on a small jelly-covered hand that shot up into the air. "Can I go to the potty?" Apparently my class was not as excited as my teacher had hoped. A small light bulb flashed above my head, however, as an idea came to mind. I'll go to work with Daddy! I decided. That way I can grow up and still watch cartoons, just like him! My father is an animator for Disney Studios. I never really knew what an animator did, only that he came home with movies like "Aladdin," "Cinderella" and "Beauty and the Beast." We would all gather on the couch and watch, but...

...influenced by socio-cultural factors such as the medias influence in everyday life and functioning, to the role of women, acceptable and non acceptable behaviours and forms of outlets that was once seen as acts against morality and obedience yet through time and growth of a new generation it has became widely accepted. Potential directions have contributed greatly to the development of my final art works. Initially I had the desire to create a sculpture using wire therefore I had multiple trials using different wire thickness as well as sizes however it presumed to be extremely hard to handle and heavily time consuming. Upon researching different art methods and techniques I came across a new form of pencil drawing called ‘gesture drawing.’ A gesture drawing is basically a quick drawing that captures the essential gesture of a subject in its most distilled form. I thought that this proved to be quite ironic (particularly to my subject matter) I found humor in this and instantly fell in love with the idea. Then I realised that gesture is everywhere, embodies in every object, person and place. It is action, emotion, movement and expression all rolled together into one cohesive...

...catches your eye to the main idea this way. The figures are distorted. They don’t have a real sense of balance or proportion. They tend to be formed how they want. The body’s on the figures for example are never really accurate to one another or too symmetrical obviously if there’s an arm on one side their tends to be on the other side but they may not always align or be doing the same thing. In my opinion and from my point of view, no. He doesn’t have an equal or a rule book he follows. He does what he feels should be done and he leaves his representation of how it appears or should appear to him. He has his own ideas and isn’t afraid to follow them. The focal point in his painting is the figure sitting. He achieves this focal point by drawing smaller lines around it that draw your eye to the...

...In the Makers video about artist Faith Ringgold, Ringgold gives a brief summary of how she came into the world of art and what she fought for while she was an artist. Ringgold was born in the Great Depression in the city of Harlem, the center of African American culture in the United States at the time. The Harlem Renaissance had happened just a couple of years before, and it would have an influence on Ringgold’s career as an artist. She ventured into the world of art when she was young and began creating story quilts. Next, she talked about her movement to get more women representation in art museums, especially the Whitney Museum. While watching the video, I felt inspired and happy because of how Faith Ringgold, despite being a minority...

...year later, Delacroix traveled to London and studied English painters he admired. He believed his trip brought him closer to imitating Rubens colorful style. It was shown in his Liberty Leading the People piece. He continued traveling but, his time spent in Morocco changed him for good. Delacroix was breath taken by the foreign culture and that was when he died to paint Arab subjects for the rest of his career. During Delacroix last years, he spent them decorating the ceilings and walls of government buildings because his murals made him feel closer to this idol, Michelangelo. Some of Delacroix's canvases in his last year include The Battle of Taillebourg and many more. In 1863, Delacroix died in France. Besides his many paintings, drawings and watercolors, Delacroix left behind a legacy that would forever change the art world, and definitely inspiring the Impressionist and Post-Impressionist painters. Today, Eugene Delacroix is remembered as one of the world's most influential French Romantic painters. ...
