I'm so glad I came here and checked what glaced means. I looked online and only found it for sale. I had bought the same stuff she did at Joann's and started having problems with machine. Luckily, I only sewed about 30". I'm going to go clean it up as suggested by Tink's mom, if I can figure out how to hold double thread through tension disks, I'm not sure how to spot them, thread disappears behind stuff when I thread machine.
