That is a beautiful quilt! I can see why you want to make it. Years ago my ex was very interested in doing a quilt that was an optical illusion and try as he might, he couldn't figure out how to draw one. I found a book on Optical Illusion quilts and was going to surprise him by making him one but then we split up and never did. I still have the book (in one of my many boxes since I just moved) and will have to look through it again. Just might have to add it to my long to do list! LOL
