To make a cardboard loom, take a piece of rectangular cardboard and fold the shorter ends back 1â„2 inch. Cut evenly spaced 1â„2-inch vertical slits into the folded ends, leaving 3â„8 inch between each slit. A Touch of Fringe: Your kid can craft a woven wall hanging to rival the wildly elaborate ones that are all over Pinterest. It's a homemade gift that's right on trend.
