Yarn and WPI Gauge Chart

Developed by MisterStiltSkin of Australia, this very handy Yarn Gauge and Wraps Per Inch (WPI) tool is essential for working out the thickness, and average weight of a range of yarns.

Indispensible aid for all hand spun yarns, and yarns with no label information. The Reference Chart on the flip side is a guide of recommended needle and crochet hook sizes as well as conversions between metric and US Imperial sizes for each weight established.

Laminated and in a distinctive orange colour, this will be a go-to guide in your craft tool kit.
