I am presently repairing a 12 yr old quilt l made for dd which her young dog got hold of a corner. I was pleasantly surprised to see all the quilting stitches beautifully intact though a few places it is looped due to her cats' claws. I used serger thread to quilt it back then when l used my Bailey midarm. I now use Glide...l hopes it performs as well. I will never use all cotton thread.
