Gorgi is now offering white fitted cots sheets in the same wonderfully soft percale all our sheets are made from. We find that many parents using sleep sacks require only a fitted sheet, particularly in warmer months. Our fitted sheets are finished with elastic fitted the full way around the the edge of the sheet for a completely snug fit, we don't like the look of creases and sleeping on them is worse. Tailor Made in NZ, allow 2-3 weeks for delivery. Please let us know if you require a custom size.
