This is the best craft store in the Dayton area!! Don't let the size of the shop fool you, it's huge on the inside! Be prepared to spend a decent amount of time there, because the owners fill every nook and cranny with items for sale! The first time I went there, I was overwhelmed by the selection, but then you see that it's laid out very succintly and can be looked through quite easily.
They specialize in yarn, stained glass, painting supplies... well pretty much everything!!
