I used the Press & Seal for a quilt I did a while back...I was using an old Singer machine and the time so warranty was not an issue, but I tell you it was the biggest nightmare I've ever gotten into! I had more problems than you could shake a stick at and hated every second working with it.
It gums up your needle, which gums up your thread and machine, your thread breaks often! Then when you finally have expanded your vocabulary until the air is totally blue in your sewing room, you have to tear off the silly stuff. When doing that...you really chance tearing loose all your stitches. Believe me...use the golden thread paper...it is wonderful...heck...using a roll of toilet paper for your borders works tons better than the Press and Seal!
