All the fabric I use for the top/front layer is 100% cotton.  The lining layer varies some are 100% cotton and some are 95% cotton and 5% polyester.  They are Washer and Dryer safe so make sure you wash them first before using.  Note: I have 7 cats so there is no escaping the fur.  I've also added some FREE stuff to the end of the list so feel free to order any or all of them you like.  I'll be adding more over time so check back here from time to time to see what's new.
