I had an odd shaped (12 sided) wall hanging that I definitely didn't want to bind. When I birth a quilt I always could see the edge I hand sewed so I did this one differently. I split my backing down the middle and sewed it together from one edge to about 8" from the center; then I sewed it from the other edge to about 8" from the center leaving an 8" opening. I pressed the seam open, also pressing the unsewn area as part of the seam (I used a 1" seam allowance). Then sew the backing on and turn as usual but when you go to birth it you have a larger area to reach into all the corners to get perfect points. I then use a blind stitch to sew the rest of the seam on the back and then quilt. All edges are smooth, points are pointy, and I had no shifting or lumps.
