I am wondering how to prevent and remedy knot migration.
This must be a problem that machine quilters never face. It happens when I am quilting and find a knot, that was part of the piecing, suddenly sitting on the surface during quilting.
I've tried back-stitching the first stitch when piecing without great success. The only thing I can think of is taking several back stitches and then cut off the knot. Any ideas? or am I the only one with this problem?
