Wraps per Inch tool
This tool lets spinners, knitters and crochers easily measure the Wraps Per Inch (WPI) of their yarn, helping them determine its weight. Just hold your yarn against the indentations in the tool to see which one most comfortably fits your yarn.
This tool is ideal for spinners wanting to maintain a consistent yarn while spinning. Attach the tool to your spinning wheel or orifice hook and you'll always have it on hand to measure your yarn in progress.
This lovely item has been laser cut from domestic Cherry hardwood and hand finished by the lovely Katrinkles in the USA.
