I would suggest rice bags also, but we use feed corn like you feed animals, heat for 1 1/2 min or freezer. Everyone that gets one loves them. Also, I use the plastic lids from jars make two big circles like a saucer or dessert plate and another one inch bigger. Place the larger one on top with the lid in the middle of the sandwich fill the lid with fiber fill and sew around the lid (hand sew) it will form a hat use scrapes of ribbon, ric rac, etc. to decorate your hat pin cushion.
