Rainbow Loom is wildly popular in America right now - and especially in my house. My son Ryan wanted to BE a Rainbow Loom for Halloween and we figured out how to do it. You can see the rest of my family's Halloween and few more Rainbow Loom photos here.
Step 1: Measure and Plan
Take careful measurements of the loom, and the person who will be wearing the costume to calculate proportionate measurements. Use the height to determine a "multiplier" between the loom height and the wearer's height. Our loom measures 10 inches long. We wanted the costume to be roughly 36 inches for Ryan so we used a multiplier of 3.6.
