Handmade Amish swift, I made one for my mother in law and she liked it. So I made a few more and sold them. I've made quite a few of them now and have different versions in my shop too.
Its full dismantlable, so you can pack it away when not using it.
THIS IS THE STANDARD SIZE OAK ONE
They all do exactly the same thing (spin round and stop your wool getting tangled up as I understand it).
There is absolutely no practical benefit in the oak one other than its enjoyable to work with from a woodworking perspective and i think it is prettier.
They are listed separately in the cheapest 'swifts' section in my shop.
The product is finished in Danish oil. I've sold quite a few of these now and the feedback has been great. So there you go if you need one of these things this is where you can get one, well made and priced reasonably live and direct from the North East of England.
