|Picture batt from California trip with Beaver, Navajo plyed!|
Basically this is a method of taking a single strand of yarn and plying it into a three ply - stronger and more round for knitting. It also allows you to play with the changes in a colorway while plying to either keep them together or to blend them in the ply.
I have practiced on two skeins now. I really like it and go way to fast. My grandma nearly despaired of ever teaching me to so because I have a lead foot, apparently it is two lead feet Grams!
