Actually, the curves on this quilt were very easy to do because they are gentle curves. The author says to clip the curves if you need to so they will lay flat, but I did not need to do this step. Trying curves is very much "out of my box" but I am very impressed with this author's explanation. I'm going to try another one out of her book called "Double Pagodas". My daughter thinks it is really cool looking, but it looks like a Log Cabin on drugs!!! We'll see!
