It would be great to have your leftover sock yarn added to mine for the mitered square blanket that I've started. It's always fun to add more colors and I think your leftovers would blend in fine. Thanks!
I've emailed Sandy and as soon as I get a snail mail address back, the box will be labeled and ready to mail next time I get to a post office.
The number of knitters wanting my leftover balls was a surprise. If anyone else has little leftover balls they'd like to donate to someone who will love them and use them, check out the comments on this blog post. Once you've picked a worthy recipient, email me for the corresponding email address.
Or, have a little contest of your own. It was fun.
