A triangle loom consists of a triangular frame with a 90 degree angle at the bottom and 45 degree angles at the two upper corners. The frame can be made out of any wood that is smooth enough so that it does not snag the yarn. Nails are pounded into the face of the frame close the inside edge. These nails are usually 1/2 inch apart on the top rail and approximately 1/4 inch apart down each of the sides. The wood should be predrilled for the nails to prevent splitting.
