I have a ballwinder, but I don't rewind skeins unless I am splitting it to make a pair of socks.
I want a swift because I have some yarn a friend game me that is kind of smelly and I'd like to wash it first. I wrapped my own hank using my computer chair, but I had a hard time winding it after washing. I'd also like to see if regular Red Heart Super Saver is softer to knit with after a good wash with fabric softener.
My best friend said buying the $37 swift from Schoolhouse Press would be cheaper than making one, if you count the time spent as part of the cost. I'll probably end up with that one eventually.
