Grateful but very overwhelmed with all this fabric. Any project ideas?

My MIL brought me over all this fabric that she got from a friend. Although I'm super grateful, I'm also very overwhelmed. It was two trash bags full! There's a huge variety in type. Some are really thick material, others are velvet. Some are thin shower curtain material? One or two are silk or maybe fake silk? I'm not sure what all the different types of fabrics are called. I don't even know where to start.. maybe just a bag of some sort? Any ideas?
