Need help with cloth simulator

So I haven’t used the cloth simulator in a good long while, and the last time I did was when I was using tutorials with much older versions of the program, and I don’t remember this ever happening before. I was trying to make blankets for a bed I modeled, but for some reason, the cloth seems to just keep collapsing in on itself.

Also these are the settings I’ve been using in the animation:

Well, I figured out the problem I was having. It looks like I didn’t have enough subdivisions on the model. I don’t remember ever having a problem with it before, but I suppose the subdivision surface modifier I had on the blanket model could have been messing with the cloth simulator too.
