Anyone who loves Mexican food loves a fresh warm tortilla. And if you aren't fortunate to get homemade tortillas every time, you might suffer from the dilemma of how to warm a tortilla so that it is still warm and pliable. I learned how to warm tortillas from my mother, who to this day probably still warms her tortillas directly on the burner. I did it this way for many years too, but I found that it dries out the tortilla. I personally hate a dry tortilla cracking and spilling its contents. I'm not a definitive source on tortillas, but this is what has worked for me in my experience.
Flour tortillas. Wrap the tortillas in a damp paper towel, and reheat in the microwave.
Corn tortillas. You can do the same trick with the damp paper towels, but I find that sometimes tacos made from these corn tortillas will still break. Lately I have been using a new trick. In a skillet, heat a small amount of vegetable oil. I use extra virgin olive oil. Spread the oil with a spatula. Then place the first tortilla in the skillet. Then flip it over and put a second tortilla on top. Then flip again and place a third tortilla, etc. Continue in this manner so that all sides are evenly coated with the oil and heat through. If there is too much oil after reheating, just dry the tortilla with a paper towel.
Hope that helps with your tortilla eating adventures!
