It's Monday and just as I thought, I have my Thimbleberries Twister quilt on the design wall/floor. I really didn't like the layout when I first finished piecing the top because the pinwheel designs in the center of the sides and top and bottom just ended. It was like I didn't finish the design. (If you look closely you can see what I mean on the bottom.)
Anyway, I decided to add pinwheels to the borders but I had to "play" because those blocks are 15 inches and I didn't have enough border fabric; plus I didn't really want to add 15 inches of a relatively plain fabric. After trimming the blocks on two sides, and adding another fabric, I like the results. I do have to do some tricky piecing to make everything work, but I think it's worth it.
