Many textile folks do not see themselves as being able to draw and since it is illegal to copy they find themselves working commercial designs.
This method of working is fine but they never really have the opportunity to try their hand at design. There is nothing quite like developing your own.
One way to ease yourself into the process is to try adapting commercial clip and copyright free art.
Dover publishes books of clip and copyright free art which means it is legal to use, adapt and remodel their designs. You can sign up for the Dover Sampler. It is free and a wonderful introduction to their product as each week they send you a selection of samples from their books.
You get some real gems and of course discover what is inside their books! This in my case occasionally proves fatal but I guess that is why they are doing it.
For instance last week this Japanese design of three fans really appealed to me.
Also in this weeks sampler is this inspirational piece. It just great eye candy to get ideas flowing.
I am not affiliated with Dover in any way I just think their clip art is great.
