Thanks. I wondered about this myself. I am making a Robot quilt for my daughter's school room, and am having fun with it. Unfortunately, I was too involved with the appliqueing of the many shaped Robots and forgot to remove the paper backing before sewing it to the quilt top!! I've now removed half of each Robot's sewing, and am hunting a long pair of tweezers, which I'm sure I had a few weeks ago.
I guess it means another trip to JoAnn's today. And I'll probably find a lot of other stuff that "may come in handy one of these days" and spend far more than I had intended when walking in the door.
