My grands learned to make these as their first sewing projects. I have a lot! I keep batting and fabric cut into HSTs for them to sew. They make all sizes. We put rice in the bottom point to keep it upright and not rolling over. Tip: They use a big safety pin to bring the top part together. Easier for little hands then needle and thread.
