I then threaded all 240 threads through separate heddles and then sleyed, (scroll down a little) them through the reed. (Note, the author of the sleying entry threads their loom from front to back, my loom is done back to front, so all their steps in warping the loom are the reverse of what happens on my loom.)
I tied the warp on to the lease stick,
wove a couple of inches with old loom waste and string to spread the warp threads evenly,
wrapped the chosen colored rags on shuttles,
and commenced to weave.
I'm not pleased. I'm using 8 threads per inch/3.2 per cm, 1 up - 1 down and find the resulting rug just too thin. I think I'll go back and rethread the heddles to 2 up - 2 down and try again.
A lot of work to reach a point where you realize you need to go back and do it over sure, but, better to fix the problem now than to try and go forward to an end result that you already know is going to be a disappointment.
