Made from Poplar, this beading loom is expandable to 22 inches. I used a two foot long piece of 1x4 Poplar (cut in half), two four foot long 5/8inch Poplar dowels (also cut in half), a spring for a storm door (again, cut in half), 6 standard nails, and four screws. I drilled four holes through each 1x4 piece for the dowels to fit through, then marked the dowels with inches. I then drilled tiny holes halfway through the dowels every inch for the pegs to hold the movable piece in place. That piece is actually pretty tight and doesn't move by itself, but I did it anyway just in case. The spring was carefully cut in half and two rings on each side bent outward and then drilled into the tops of the 1x4's. This keeps your thread evenly spaced and provides stability. Three nails were then hammered into the outer sides of the 1x4's to tie your thread down. Things to keep in mind that if you were to make one of your own:
1. Sand down all of the edges of the 1x4's because sharp corners can fray your thread.
2. Drilling the holes for the dowels can and will rip your wood. Drill each hole until the tip of your bit pokes through the other side, FLIP the wood over and drill the rest from the other side. This technique made for clean holes.
3. Drilling tiny holes halfway through a dowel can be hard, I used a vice grip to hold it steady.
4. The storm door spring was a pain. They're very hard to bend, cut, and screw into place (it had to be screwed in on one side, then stretched and held while the other side was screwed in). Not something for one person to do alone!
A beading loom of this size, stability, and the fact it can be re-sized can be pretty pricey on the market. There's one that matches this on firemountaingems.com that's selling for $160. This was $14, one hour, and two people.
