Previous pinner said: Made this last weekend. 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!
You can do this one of 2 ways. Find inexpensive pillow cases and sew them together or find an clearanced or inexpensive twin sheet - fold in 1/2 lengthwise and sew in pillow compartments. That way pillows can be removed/replaced when needed and cover can be washed.
