3D-Printed WPI Gauge

These little tools are incredibly useful for measuring your wraps-per-inch (whether handspun or commercial) and for keeping track of your yarn weight while spinning. If you're not sure whether your yarn is a DK or sport, you can check your WPI using these colourful little tools. 

Available in multiple colours, they come with a handy steel key loop, so you can attach it to your project bag, spinning wheel or belt loop. 

Printed in the UK using 100% PLA (sustainably sourced bioplastic, not derived from fossil fuels).
