I am working on a pinwheel quilt now with little 9 patch blocks in the sashing. When I put my pinwheels together I thought "Hey that wasn't so bad". Then I sewed my pinwheels to the sashing strip and nothing was matching. I wanted to pack it all up, but I spent a lot of money and this is for my bed. I realized that I needed to square up my blocks. As soon as I did that EVERYTHING started going together great. So stick with it you will be happy you did and it is a wonderful learning experience.
