I have tied all of my quilts or comforters. Reason, we live where it`s cold and use high loft batting. I have one comforter left that I cannot give away as it has wool in it, and young people don`t know how to handle it. Also it is wise to knot the wool ones at 4 inches, this will hold the wool in place better. I knot with all of the threads mention here to-day. My children liked to twist thier fingers around the knots before they fell asleep. Also the frames mention here can be call quilting sticks. I resently had a carpenter make me a new set so I can make king size quilts (110X110 in.) I have a large room to set it up in.
