I just finished binding my 4th quilt, this one is crib size, and I'm just not getting any better at this. It seems that no matter how carefully I cut, or slowly I sew, my piecing never seems to match up. I pin carefully when I make the sandwich, but when I stitch in the ditch there is inevitably a pucker somewhere, and I get areas in the quilt that look "pulled" in a direction. I use a walking foot, sew slowly, but by the time I'm binding it I think it looks awful. I find it difficult to sew a 1/4 inch seam on the edge of the quilt when binding, and the quilt back ends up a little smaller than it was when I cut off the excess backing and binding. I would love some tips to just "clean up" my technique. Or, am I expecting too much?
