No matter how hard I try to sketch with a pen and paper my doodles always turn out horrible. I am more comfortable using my ipad and drawing in illustrator which is what I did with the above patterns. I saved the line art as .jpg and opened them in photoshop and followed your directions. The class was easy to follow and I was able to make a few patterns.
I did have a question though ... when I filled the the layer with my pattern it automatically goes to 100 percent for the size. If I resize lower than 100 percent the patterns get blurry ... do you know why that is?
