Previous pinner said: Used a twin sheet ( that I found for $2.24 clearance) folded long ways. Sewed 5 sections to the size of pillowcases and slipped the pillows in. I left each 'pillow compartment' end open so the pillows can be removed and we can wash the cover. Kids love it on the family room floor!
