Have you ever purchased a cone of yarn and don't know how much yarn you really have? It's easy to find out, by using our Yarn balance. The Yarn balance is a scale that allows you to determine the yardage of a particular yarn. Replaces the original McMorran Yarn Balance which is no longer available.
Using a Yarn Balance
Place the balance on a level surface, such as on the edge of a table & set the pins of the small balancing arm into the small notches on the top of the box. Lay a length of yarn in the notch of the balance, allowing the yarn to hang.
Using scissors start to trim the length of yarn, cutting a little at a time, until the balancing arm is level.
When the arm is level, remove the length of yarn from the balance. 
Measure the length of yarn with a ruler.
• Multiply the measurement x 100.
• This measurement gives you the number of yards per lb. of yarn (ypp).
• e.g. 8.4 inches x 100 =840 ypp.
If you are measuring bumpy, slub or a handspun yarn, the measurement may not be accurate due to inconsistencies in the yarn but it will give you an approximate estimate.
