they are so much fun to make--- the top square is larger than the bottum by 1/2 inch i stuff with fibir fill when i make them for the intensive care unit but at home i stuff with fleese, batting and anything else i can find. great way to get rid of scraps.. then back'em and i tie them. i was just thinking ---you know those squeekers you can buy at petsmart for dog toys you could put in a couple those and watch what the babies do when they find one. they love to pinch and pull at the fabric.
