Instead of one type of yarn, our weavers use two, which creates a subtle plaid and heathered texture. What's even better is this special weave—plus a triple-brushing technique—results in a flannel that feels so soft and snuggly that you won't want to get out of bed. An extra set of matching standard pillowcases is available separately. Sheet set includes a flat sheet, fitted sheet, and pillowcases (twin, one standard; full and queen, two standard; king, two king) Twin fits mattresses up to 13" deep; full, queen, and king up to 16" deep Extra Pillowcase Set includes two standard pillowcases 100% preshrunk cotton flannel Machine wash and dry Made in Portugal Exclusive to The Vermont Country Store Coordinating Heathered Double-Flannel Blanket (#78140), sold separately
