One year, I made 12 full sized quilts and tied them all. Different things happened to them. Some tore where the yarn was tied. Some of the quilts were on a bed that was jumped on by the kids. No good, they tore. If you are going to tie the quilt, make sure to follow the batting's instructions on how close to tie. If the quilts are going to get a lot of use, I would stitch close to the ditch with the machine instead of tying. Just a thought..... Irena
