I've had a lot of trouble positioning the lease sticks so they are easily visible when I'm warping my 4-harness Baby Wolf. I've tried every chair or bench I can find and I'm always too high and have to contort too much. Yesterday, I decided to raise the four harnesses and searched for something that would raise them up while I finished warping and sleyed the reed.

Voila! A yoga block to the rescue. It raised them just enough that I have perfect line-of-sight through the heddles to the lease sticks. I finished threading the heddles and sleying the reed without the back, shoulder, and neck pain I usually have when warping the loom.

I'll try to upload a copy of the picture.
