This may be a silly question, but have you tried covering them with a 
dishtowel? One large enough to tuck under the edges so the heat is 
trapped inside. I also place them with the towel over them, on the 
stovetop, with the oven set to "warm". Figure out where the vent is 
for the oven and place them close to  that. If they seem to get more 
warm on one side because the vent is in the back, then turn them periodically.
