Portuguese masters with decades of expertise weave our flannel sheets. The cotton is combed to remove impurities and shorter fibers then brushed three times for the softest touch. In printed striped patterns for subtle interest, this set is toasty warm, but light enough for year-round comfort. 100% cotton. Machine wash. Made in Portugal. Twin sheet sets include: one pillowcase, fitted sheet, flat sheet. Full, Queen and King sheet sets include: two pillowcases, fitted sheet, flat sheet. Pillowcases: set of two.
