I've been eying D.I.Y.: Design It Yourself in the book stores for quite some time now. I picked it up tonight, and I just wanted to say that so far it's an excellent read!
DIY won't make you a designer, but it gives you simple tips, and ideas to use as inspiration for projects featured in the book. CD cases and covers, towels, tee shirt designs, and SO very much more are covered. Hell, even blogs!
