So I did a large group fondant thing and was trying to think of a way they can use the corn starch. I've heard big "no no's" for using nylons and getting shakers or those dinky wilton ones is too expensive.
So the answer is cloth diapers!! Not the tri-fold ones, but the big thin ones.
They're 100% cotton! And they work great! I cut one up into 6 and sewed the raw edges, but you can probably get even more out of it
