"Use a twin sheet ( look for clearance sheets) folded long ways. Sew 5 sections to the size of pillowcases and slipped the pillows in. Leave each 'pillow compartment' end open so the pillows can be removed and the cover can be washed."
Giant Kerplunk!! this was the hit of father's day. the link for instructions is posted next to this pin on the same board. I used 3/8" x 3' square dowels instead of the bamboo plant sticks. The bamboo did not work very well. My mother (89 years) and one of my grandsons (3 years) loved playing it. Have fun!
