My newest fiber toy is an attachment for my spinning wheel called a WooLee Winder. Most wheels come with a flyer like the one in the picture below with little hooks all around edge. To wind the yarn evenly on to the bobbin you need to move it down the hooks every few minutes.
But, the WooLee winder is different. It's hard to see in this picture, but there is one loop that the yarn goes through. This loop moves back and forth along the length of the bobbin. This results in yarn that is very evenly distributed along the bobbin.
This mechanism works because there is a gear on the flyer that aligns with the one on the bobbin.
As the bobbin turns, the gear on the flyer turns which controls the movement of the loop up and down the bobbin.
This means that you save time by not having to stop spinning every few minutes to move the yarn onto a new hook. Also, with such evenly distributed yarn (along with the slightly bigger bobbins) you can fit a whole lot more yarn on to one bobbin.
So far I really like it. I have spun up 2 skeins of yarn. It did take a little while for me to get used to the tension of the woolee winder. It seems to add quite a bit of tension to the yarn. Once I figured this out and turned the tension on the wheel itself almost all the way down I was good to go.
The first yarn was one that I dyed a while ago with kool-aid. It is Tesswater wool from my Paradise Fibers fiber club a while back. I divided the roving in half and dyed half with cherry and the other half with grape. (Must have forgotten to take a picture of the grape half. Oops.)
Here they are spun into singles. There are 2 oz of fiber on each bobbin with plenty of room to spare.
I then plied them together. The picture is a little washed out but you get the idea.
