Thank you so much, you just made me feel pretty good about myself, hehe. I have not read either of her books myself, but I definitely plan to. I love this craft just for the fact that you can just experiment without having a specific plan in your head, and you never know what you'll come up with! I am really looking forward to seeing your creations. My favourite cokour is definitely green, but I just love anything bright. I can't imagine ever doing a project that wasn't full of colour! I frequently use my kids old clothes. I would think the only limitation would be to not use material that's too thick because your machine would probably object!
