This blog post was originally published about 7 years ago and deals with a problem that most weavers encounter - what to do with empty yarn cones. Sure, you can throw them away, but weavers are a thrifty lot and many are uncomfortable with that obvious solution. The search has continued for a better recycling idea.
It turns out that Pinterest has dozens of pinned solutions from many crafters/artists and probably a lot of primary school teachers.
(I had an ulterior motive for reposting this article. Now I have a link to share when I'm handing out free cones.)
