I put together some kits for those wanting a dead simple introduction to needle-felting.
Using only natural undyed wool, dryer balls help to reduce drying time when using a clothes dryer. They're good for those that are sensitive to dyes and perfumes, and though not advertised for this purpose, they make a fun play ball for kids too, as long as those kids are old enough not to take a bite and get a mouth full of wool.
The kit contains:
3 felting needles
A reusable felting mat
3 colors of natural wool for the outer layer
Each kit makes 3 balls about the size of a tennis ball.
They're in my shop.
