They're an acid free cardboard. They're really pretty sturdy and cost about $10 for a package of 100. Since they're acid free they won't damage your fabric. I did feel a little silly going into a comic book store - but hey I was on a mission. They have different sizes - comic books, magazines, etc. - so you can get the size that will work best for you. There's also a video on YouTube that shows you how to fold your fabric.
