So simple! Wool dryer balls made from scraps of upcycled wool sweaters, wool ends of yarn, and wool roving. They can be used as dryer balls to cut down on drying time and save energy; or as cat toys (add a little catnip or a small bell inside before felting); or dog toys; or soft playtoys for toddlers to toss and catch.
How to make wool felted balls:
1) Make a small bundle of 100% woolen sweater scraps. These can be off-cuts from any larger felting project you've used your sweaters for. Any colour will be fine as you won't see this inner core once the ball is finished.
2) Wind 100% wool yarn around the woolen sweater scraps tightly. Wind into a small ball, several inches in diametre (completely cover up the woolen sweater scraps with your yarn windings).
3) Then wind layers of wool roving in colours you like (these will be visible) around the yarn ball. The thinner the layers the better.
4) Stuff you wool ball into an old nylon stocking and tie up tightly to secure.
5) Repeat with as many balls as you like, to fill up the whole nylon.
6) Wash on hot, 2-3 full cycles in a load with towels. Wool will be tightly felted once you are done! Remove from the nylon, let balls dry. Then use!
For dryer use, they can be sprinkled with a bit of pure lavender essential oil (or other scent) optional. Use 2-12 per load (more balls decreases drying time).
We LOVE these balls to toss around with our toddler, and for our cat to play with. They make lovely gifts, simple and recycled, and useful too.
