I recently celebrated my birthday and as a little gifty, I purchased the book Digital Textile Design by Melanie Bowles and Ceri Isaac. The book gives really clear ways to use Photoshop and Illustrator to create textile designs. After discovering Spoonflower I really wanted to be able to create some repeat patterns and voila! this book shows up while I am perusing the shelves of my local bookstore. I'll post some designs when I get it all figured out!
