I knew it would (theoretically) but I didn't really think it would, really. Years ago, I made some "hot pads" out of old squares that I didn't feel like making into an afghan. I doubled up the squares, sc them together and have been using them on our dinner table to set platters/bowls on for family dinners. Here's a photo of what hot dishes will do to acrylic yarn. for some reason, I thought that it would take really, really high temperatures to melt yarn. Like, put it directly in the fire hot. Now I know, and so do you!
