I don't sell, or put my quilts in competition. I don't want to be professional, I just want to enjoy the look on someone face when I give them the quilt. I try very hard to make all seams meet. When quilting began I don't believe they had sewing machines, it's just the "perfectionist" in us that wants it that way, but does it really have to be. Do you actually notice one block off a scant over the other. Okay in competition, but not in my everyday life. I use a 1/4 quilting foot, if the seams not right I always allow for error. But if it's not perfect, then "Oh Well" keep trying. I want my quilts to be used, abused, loved, dragged, or whatever. I do see though that as I keep making, the seams are getting better and consistent. If I can't smudge it correctly, then I"ll redo the block.
