I do bake mine. I put them in the toaster oven on about 220 degrees for about 20 minutes. I let them cool down also in the toaster oven. I haven't been baking them for too long but so far so good. I have scrunched them over and over in my hand to test them and they always bounced back. I also used stiffen stuff before baking them but I don't care for the bows to get that stiff so baking is great..
