Yves Delorme Écumes Organic Cotton Sateen Bedding Collection - Duvet Covers, Flat & Fitted Sheets, Shams and Pillowcases in Multiple Sizes

This is the Yves Delorme Écumes bedding collection, a woven damask cotton sateen bed linen line featuring a wave-inspired "marine undulation" pattern that rises from the fabric surface to create a textured, light-catching finish. The collection is designed for use on beds in adult bedrooms and includes multiple linen formats sold as separate items within one product family. What it's made of: 100% organic long-staple combed cotton, woven at a 300 thread count in a sateen (satin weave) construction. The damask weave technique produces a raised pattern that combines softness, subtle sheen, and surface relief. Product formats available (sold individually, sizes vary by piece): - Duvet covers - reversible, button closure, sizes include Full/Queen and King - Flat sheets - double 5-inch damask hem with a piped finish, sizes include Full/Queen and King - Fitted sheets - sizes include Twin, Full, Queen, King, and California King (Twin and Full/Queen/King fitted sheet depths approx. 18") - Shams - reversible, 2-inch flange, piped finish, envelope closure, sizes include Boudoir, Standard, King, and Euro - Pillowcases - sizes include Standard and King All pieces share the same Écumes pattern and organic cotton sateen construction; they differ by size and by which bedding piece they are (duvet cover vs. sheet vs. sham vs. pillowcase), not by fabric or design variant. Color across the collection is listed as "Multi" reflecting the woven pattern rather than a solid color choice.
