How Long Should the Warp be?: The frame you use toweave it should be at least 5.5 feet tall - preferrably 6 to 8 feet tall. Your warp will be double the length of your frame - so at least 11 feet long. You may not use all of the warp, but extra is needed to properly tie off the ends and finish them.
Note: My belt is to fit a 30" waist. Adjust your warp length as necessary.
What Do I Weave the Belt On/With?:
A frame can be built simply out of 2'x2' lumber, or even an old door would work. The belt in the above picture was woven on a standard-size door. Lacking a suitable door, the 2'x2' and a small miter-saw to make the frame shown below should be available for about $20.00 USD at any hardware store.
Our frame is held to the ceiling with two hooks and wire.
