How to Make a Hexagon Loom

1). Draw a hexagon on your plywood. It can be whatever size you need. Keep in mind that if it is too large, it won't fit on your lap. The sides should be even and the angles of the opposite corners should match, or your woven items will be lopsided. If you want to elongate the loom, make two opposite sides longer but leave the corners at the same angles. A symmetrical hexagon has 120-degree angles at the corners.
2). Cut out the hexagon and the interior hole. You can use almost any saw on the outside of the hexagon, but you need a jig saw with a special blade for plunge cuts to cut out the inside hole. This blade is meant to start outside of the wood and then cut a hole in it, without any holes existing beforehand. Other blades may not withstand the pressure of this type of cutting. Leave about 2 inches of wood from the outside edge to the inside edge.
3). Sand the wood with sandpaper. This eliminates any rough patches that may give you scrapes or splinters while making or working with the loom. Use a fine-grain sandpaper, marked with a higher number like 800, to make the wood smooth and comfortable. You can also paint or varnish the wood for an attractive finish.
4). Measure and mark the width of the pegs all the way around the wood. This width can differ, and determines the gauge of the loom and how fine the weaving will be. A regular gauge has pegs 1/2 inch apart. Finer gauges will be closer together, with an extra fine gauge as little as 3/16 inch apart. Large or wide gauges will have pegs farther apart and result in a loose weave even with bulky threads or yarns.
5). Drill holes for the pins to go in. Use a drill press if possible, and set the depth of the drill so it does not go all the way through the wood. Use a bit that matches the diameter of your pins or the holes will be too loose. If the bit is too small, you may need to widen the holes or hammer the pins in. Practice on a scrap piece of wood to make sure you have the correct settings and bit.
6). Add the cotter pins for pegs. You can use the drill press for this as well, if you use a dowel instead of a bit to push the cotter pins into the holes. Once all the pins are in place and secure, you can use the loom.
