Been quilting fairly problem free with HQ16, but just finished a quilt and I have to un-stitch and re-quilt a sizable section because of eye-lashing on the back. I noticed it when I advanced the quilt so knew then I had a problem I'd need to deal with later. I assume this came about when I unthreaded, wound bobbins, then re- threaded. I'd appreciate some tips on how to check that the stitching is looking okay sooner rather than later. Thanks much.
