My husband is my ripper outer. He has the patience of Job but when I was a long arm quilter he undid 3 king size quilts done by another quilter in our area. She had specified cotton thread and the quilter used monofilament. She was so unhappy but my husband carefully took out each stitch and I requilted her quilts with Cotton thread. I refused to use monofillament. If the quilter insisted on that type of thread I sent them to one of the ones who use that type of thread. My momma taught me you never use a thread that is stronger than the fabric you are sewing.
