After this I wrapped them with more wool yarn and they're ready for their second felting. As the turtorial states, commercial dryer balls are about 9 inches in circumference, so to account for felting, you probabaly want to wrap them until they are about 10-10.5 inches. I only had enough yarn (I snagged some scraps from my sister too!) to wrap them until they were about 7.5, so they'll be a bit smaller. But that's okay, because you can really make them any size you want!
And then back into the sock they went, and in with another load of towels! Here they are after the second felting! They shrunk down to about 7 inches in circumference, but I think it's a nice size. =]
I just love this kind of stuff so much!! I feel so accomplished when I can make something at home to save us money and help the planet! Now I'll just have to report back on how they're doing in the dryer!!
