You can heat set by placing a protect cloth between the design and the iron and ironing the design or you can turn the material inside out and place in the dryer on high heat. If the acrylic does not require heat setting on fabrics then you should still protect the design from fading when washed. To do this place the clothing into a sink of cold water and salt and allow to soak. The use of the internet has made it where you can show your work to the world for free. Almost everyone on the internet has started using a blog. Well you should be no different. Get yourself a free blog and start showcasing what you can do. Don't just put up pictures of your work though. Make sure to actually talk to your audience. If you are doing a stencil for say a dog then you would want to take your time and make sure that the eyes were the same size, the nostrils were cut out shaped the way they should be and so on. If you rush you could end up messing your stencil all up. The stencil is to aid you in creating your airbrush art and is a big part of the art process. You will believe it is easy until you get out there and try to do it yourself. It is at this moment that you realize that you are not able to do what they did. To start with you need to practice with simple techniques until you get the hang of how to do them. Simple techniques will give you a better understanding of the process and allow for you to have a foundation in which to build on. Go to the library and check out some art books to help you get some inspiration to get you going again with your creative design. Sometimes by looking at other people's works you can get past your creative block and start creating your own airbrush art again. Any form of art will work to give you inspiration since after all you can airbrush any design you see.
