So I've done it! I set up on Etsy this afternoon, and now I have an online yarn shop.
You can visit me on Etsy at TheSpiritedSpindle.etsy.com.
Right now the shop consists of a few yarns (pictured above) that I have lying around, projectless.
In the future I will be a bit more intentional as I stock up the shop with yarns that I'm dyeing to create (sorry for the pun!).
But to do that, it's back to spinning for this spindler.
