I searched around on the net more, and saw where people were using comforters, several large towels, etc. I used a couple of kitchen towels, and it was a chilly day, too. So I think I didn't cover it very well. This time I have it covered with several big towels and a nice heavy flannel sheet. I'll be unwrapping in about 4 hours - can hardly wait! Thanks to all for all your responses!
