Sorry guys, for now this is still a yarnie swap.
Why? I mean, I'm a yarnie (and them some), but what if yarnies want a non-yarnied hat? Why can't we have qs on the q'airre saying "what can you make?" and "what do you want in return?" That would be cool. No hostility! Just going for discussion with this because this is a discussion thread, right?
There are a few reasons why its a yarnies swap. Foremost is because its meant to be a low pressure swap for all involved, including the organizer! And adding non-knitting/crochet hats to the mix makes matching up partners a lot harder and creates more opportunity for one partner to feel shortchanged.
A secondary reason was originally this swap was started as a chance for yarnies to show off their skills. That being said, extras have always been allowed and non-yarn crafts can always be negotiated between partners.
