I had never seen a center pull ball until a couple of years ago when I started knitting like mad after many years away. My LYS did the winding and I then learned from Amy's video how to make one of my own. But my husband had been with me when I bought yarn; he noticed the winder and swift. I have a rule that things I would never buy for myself go on my Christmas list. My racing friend got me the winder and my brother who doesn't even know what yarn is conspired with my husband to get the swift from a LYS. Clearly, I don't really need them as I can have the yarn wound when I buy it at the LYS, but it sure is nice to have at home.
So ... put both items on your wish list and see if maybe you get some Christmas magic!
I do have to admit: my husband grew up winding yarn for his mother ... maybe the winder was self-defense!
