Here is the main link I looked at to figure out how this works and gave me the inspiration for the peg board.
Step 1: Draw the grid
Using a sharpie I drew a diamond grid that teh rope will follow while creating a mat.
In order to fit larger size rope as well as small I made the diamond grid 3 holes on each side.
I drew a border around the outside to remind myself to leave room for screws and such.
Step 2: Draw the Cross overs
This shows where the rope will either cross over itself or under itself as the weave is created.
Step 3: Mark moveable peg lines
Step 4: Board backing.
Step 5: Glue the pegs
16 of those pegs will be glued and 16 will be loose.
Glue the pegs on the left and top side at the apex of each diamond.
The other 16 pegs can be stored in the holes along the top when not in use.
Thats pretty much it for the loom. You are now ready to start playing.
