I've purchased tablecloths, placemats, and napkins in Melchor, but haven't found anything like bolts of the Guatemalan textiles, and I only know of one shop that even sells the tablecloths. Prices are very reasonable, but not a lot of selection. As far as things like blankets or bedspreads, you're more likely to find neon-printed fleece imported from China than anything hand-crafted in Guatemala when you shop in Melchor.
