Using your Sferra Catena flat sheet is easy. Just lay it on your bed and tuck in the edges. For the best look, pair it with the Grande Hotel white fitted sheet and the Catena Duvet Cover. When it's time to clean, machine wash it in warm water on a gentle cycle. Avoid using bleach as it can weaken the fabric and cause yellowing. Also, don't use fabric softener. Wash dark colors separately to prevent color bleeding. Tumble dry on low heat and take it out while it's still damp. You can steam iron it on the 'cotton' setting on the reverse side of the fabric to keep it looking its best.
