How do you make a home made rainbow loom?

You can make a simple loom for rubber band bracelets by pushing pushpins into a wooden board. To imitate the popular Rainbow Loom, arrange three rows of 13 pushpins each on a narrow wooden board, each spaced about 3/4 inch apart. It's helpful to use a hammer to drive the pushpins securely into the board. Ask an adult to help you. See link below
