I looked up how to make them myself.

And ended up buying them at the Farmer’s Market 4/$12.

Drier Balls

People may be getting these for gifts.

Best yet, they are super cheap and easy to make!

What you will need:

A roll of 100% wool yarn (between $5-$10 on average)
An old pair of tights (or at least one leg of an old pair of tights)
Yep, that’s it!

How to make ‘em:

Start by wrapping the end of the yarn around two of your fingers 50 times. Then slide it off and wrap the yarn around the bunch to secure it. Keep wrapping the yarn, slowly forming a ball, and then building on the ball until it is about 3 inches in diameter. Tie off the end and tuck it under one of the loops to secure it and prevent it from unraveling.
