The bags are simple "bayongs" (shopping bags) woven out of natural fibers. You can buy usually them in a variety of sizes at the local wet markets. Acrylic paints stick well to them.
The original idea for this craft came from Fine Lines, a great blog from which to get ideas for crafts to do with your children!
The original idea for this note holder came from this website but we made some changes due to lack of certain materials in Manila. They still came out amazingly cute! Love the crossed eyes!
