I do the same thing that Scissor Queen does. You can't back stitch when you chain stitch. At first I had a terrible time not back stitching since I usually made clothing and it was habit. My quilts stay together with no problems. I do shorten the stitches--I think it makes them more secure. Those of you who have problems with the stitching coming apart are probably using to long of a stitch. imho
