I recently got a ball winder as a gift, and though I want
a swift, I use an idea I saw on the internet: a lamp. I remove the knob at the top of the shade, place the hank around the shade, attach to the winder and begin to wind. I found as I am nearing the end of the hank, it becomes wide enough to slip off the shade: I place a hand as a guide (like a u-shape) to hold the hank out a little and keep winding. And yes, I unplug the lamp first!
