Don't put packing blankets in the dryer

I have some nice packing blankets I picked up from Costco which I have been using to protect my car when I put stuff in it and also to go over my couch. I made the mistake of washing them today. Well, that wasn't the problem. It was the drying part. Now they have burn holes!

Warning to everyone who likes packing blankets: wash them all you want, but do NOT machine dry!
