I'm in the middle of a drunkards path quilt. The first half of the pieces went together real well, no pinning (I saw something on line about not pinning and it worked great). Then as I continued, I lost something in my own approach because I couldn't get them to go together as well without pinning. They were all cut the same direction from the fabric, same template, etc., so I started pinning in the center and on the ends and those are together fine too. It was my curved piecing challenge to myself. I'm almost done with the top. I didn't use any special feet. the problems I think are mine!!
Maybe you can practice on some scraps and see how you can put it together.
