I do like to use a good quality thread that will hold up. I made one quilt for my nephew that stitch up fine. But, after a few washings, the quilting thread started to break, and break, and break. Nope, I will not use a poor-quality thread anymore, learned my lesson. After that quilt, I stepped my quality and haven't had a quilt fall apart since (well, if you don't count my sister's flannel quilt that started to fray and split seams after 20 plus years of daily use and many, many, washings.
