I wanted to make a rope mat so i googled how to make one. There were plenty of templates to draw to show where the rope cross and such, and using nails on a board to hold it in place while you get it started. I decided to make a peg board loom that would allow for making different sizes of mats with various numbers of Leads and Bights.
The pegs are glued in place on the left and top side. The bottom and right side are left open to allow for free placement of the pegs to set the desired size.Here
is the main link I looked at to figure out how this works and gave me the inspiration for the peg board.
