Dry Goods, Roofless

I have assembled Harper's Dry Goods for my Old West town, but there's something missing--the roof (and walls). The kit came with three packs of glasses wipes, which I'm supposed to coat in white glue and then spread over the roof and wall frames. That's going to be a messy job, but if I do it right, I may wind up with something more interesting than the typical wooden slats seen on other Old West buildings.
