We already have a Michaels and a Jo-Anne's in the immediate area (and I always wonder how either stays in business). Personally I would have much preferred a Harbor Freight, it fills the hole between dollar store and Lowes where I can find a cheap version of the actual tool I need (but only need to work once, not forever).
Yeah, I'm trying to see how the area supports yet another kind of that store. But I don't know how these decisions get made.
We seem to have no end to auto repair places, tire and battery stores, chain restaurants, fast food places, and steak houses. You'll pretty much never run out of gas in most parts of St Mary's because of the abundance of gas stations.
Convenience stores, u-store-it places.
But my guess is still, when you choose to start a business, you have to get the idea of what the shopping public is like, here. We're at the end of a peninsula - ain't gonna be a lot of "through" traffic down here for shopping.
I don't see this area as a real "craft-y" kind of place.
