I have rented an Ashford Kiwi. It’s actually a brand new wheel; I am the first to rent it! It needs a little oiling but is working fine. I spun up some mohair wool blend and that seemed to go smoothly. Now I’ve got some alpaca marino which is a little more troublesome. Very slippery.
And having to use threader is a little tiresome but easy enough. It is double treadles which actually hasn’t been too difficult to adjust to.
At the shop, I tried the Schacht Ladybug and liked that. But I couldn’t rent that one.
I think the Kiwi and I will become friends. It’s very compact and sturdy. And it does treadle smoothly.
