I have already cut one towel off before this one, so my tie-on knots aren't in this photo. If this was the first sample, this is where the knots would be.
Attach the final cord close to the end of the warp. Make sure the rod goes through the proper hole in the cord, unlike me, in two pictures above, where I put it in the second hole, instead of the first. I caught it before I got too much tension on the warp.
I have a lot of baggy warp threads on this piece, because I had been weaving lace with a pick-up design in the middle, so the warp take-up was different across the piece.
The advantages to this technique are: very little loom waste, no lumpy knots to cover, and the sample can be wet finished before starting on the project. It can also be used to remove projects before running out of warp.
I hope the photos are helpful.
Here is a photo of the project I removed from the loom. It's in taking a bath right now, so the finished project photo will have to come later. It is Atwater-Bronson lace done with pick-up on a four shaft loom. The design will show much better after the bath.
