Nano Precise Wraps per Inch Card

What to do when you spin superfine and not even our Micro Precise Control Card (which goes to 80 WPI) allows you to quickly check your wraps per inch?

Our Nano Precise WPI (Wraps per inch) tool is easy to hang from your wheel or stash in your spinning bag to check WPI as you spin and allows you to estimate your WPI from 15 to 200.

To measure WPI, wrap your single 10x starting at the edge “Wrap 10” points to.  Look for the largest number not covered; that is your WPI.  If a number is partly covered, estimate WPI between that and the next smallest number.  For singles finer than 40 WPI, do as above, but wrap 20x starting from “Wrap 20”. 

Great for spinning bragging rights.

This WPI tool is made from 1/8" cast acrylic or 1/4" plywood with a hardwood veneer.

Dimensions: 2" x 3.75" inches
