This is a picture if a skein winder.  It has many names to it.  I received this from the lady who I'm making the Day Dress for as part of the payment.  I am very blessed to have gotten such a neat item.  

The term Pop Goes the Weasel refers to the pop that the gears make after 40 turns.  Supposedly there were 40 verse that goes to the song for the students to say as they wound the yarn.  There are a few different versions from what I've gathered. 

Now I just need a spinning wheel 🙂 .
