Daedalus Nano Precise Control Card
Nano Precise WPI (Wraps per inch) tool - easy to hang from your wheel or stash in your spinning bag to check WPI as you spin.
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, do as above, but wrap 20x starting from "Wrap 20".
This WPI tool is made from 1/8" cast acrylic in clear
Dimensions: 2.125" x 3.14" inches
