wool felt source?

[monkeyma]

Does anyone have a good source for 100% wool felt? If it has some sort of chemical free certification, that'd be even better. I'd be using it to sew some simple picture books for DS. I used to let him have free reign of the board books, but he's started peeling the pages apart .

I usually purchase from Weir Dolls and Crafts.
