Shaft Switching Sampler

It's been several years since I took Jason Collingwood's class at Juanita Hofstrom's Vavning Studio. So I had to reread my notes and look over Peter Collingwood's books again to figure out what I was doing. I have the new Cranbrook warped with linen for a sampler and I made some shaft switchers out of some wood strips with nails. All I have left to do is make the doups and I'm ready to weave.

I want to try out some different sized weft yarns to determine the best epi. Then I can make the shaft switching device using levers.
