Tired of not knowing what size your yarn is? Have a habit of losing your yarn labels? Holding two strands together and not quite sure what size they add up to? This handy sheep will help you measure the wraps per inch (WPI) of your yarn, the key to finding out exactly what size it is.

The wood is Kiln dried. So your 1 inch should not ever be off.
