So - I went to Rhinebeck yesterday. Oh dear god I really should have taken 2 days. I'll know better for next year.
I did get my second wheel - I went ahead and got the HitchHiker and am now going to learn how to use it. I understand where the persnickity part comes from as you have to use your whole foot like a sewing machine treadle to spin with it.
Along with stocking up on some of the fibers I don't normally have close access to, I also got my first Golding Drop Spindle. It's sitting in the corner of my cube here at work, just taunting me.
and yes - that's an ounce of Bison Down beside it... now to get through the things I have to in order to be able to play.
