In this video, I demonstrate how to create your own WPI (wraps per inch) tool, and how to use it to determine the weight of mystery yarns.
The Ravelry Standard Yarn Weights chart can be found here.
The yarns I use for demonstration are Knit Picks Wool of the Andes Bulky, Berocco Vintage Worsted, and Knit Picks Hawthorne Sport.
My silver ring is actually a knitting needle gauge, and can be found here.
The nail polish I’m wearing is by Julep, and isn’t actually a color, but I like the way it looks. It’s a nail treatment, called Oxygen Nail Treatment. It seems to help my nails grow, and prevents chipping and peeling.
