I'm so glad you posted a picture of your yarnwinder. I have never paid much attention to the things as I either have my yarn wound at the yarn store or my kids help (isn't that what they are there for??
Anyway, it brought back a memory for me of my mom bringing home her first yarn winder (it looks just like your, I think she still may have it) and us winding every skein of yarn we could get our hands on. She was so tickled with her yarn winder --I remember she got it when she was experimenting with machine knitting. This was more than 20 years ago, I'm sure.
Well into her 70s and with Parkinson tremors and arthritis, my mom is still knitting(quilting and crocheting,too!)
Now I have to call her and ask if she still has that thing!
Well, running late again and time to get the kids out of bed.
Have a happy day, all!
