A nursery essential, this 2-layered 100% cotton muslin fitted crib sheet provides soft & tender comfort for a sleeping baby. This one size crib sheet is breathable and gentle on baby's tender skin. The muslin's sturdy yet open weave and natural "give" makes it easy to use and care for. It will not only last, but becomes more supple with use. As with any new fabric to touch baby's delicate skin, always prewash cold gentle cycle and tumble dry low prior to use.
