I came across this website with a building plan for a simple triangular loom, but can be easily adapted with another end bar for squared projects. It would be great for small projects or you can even put down a weight to tie up a backstrap loom too. I get so wrapped up in looking at all those expensive looms that seem so out of my reach that I forget how simple it can be! Anyways I thought this might be a fun project for kids or beginners to try out so I'm sharing. Here's the link for the plans. Enjoy. http://www.africancrafts.com/davilojo/ed/lesson2.htm
