I did buy corn kernals but when the boys discovered sand and fiber-fill in my basement they never asked about popping the corn. I do plan on trying that at another time now that "Iwantasew" made it sound safe to try --- so we will --- next time. I posted in the "Pictures" section their wonderful creations. Myachi sacks stuffed with sand .... and a multitude of pillows stuffed with fiber-fill. It was a great day. They truly loved sewing!
