You can buy Mosaic Moon yarns and fibers right here as instock, ready-to ship yarns/fiber (when available), Clubs, and Semi-customs. We also sell through Hyena Cart, Necessitae, and Etsy.
Many customers also purchase our yarns through Co-op / Group buys which offer the additional benefit of a price break, as well as the ability for customers to order the colorways that they choose/vote on and/or special custom orders that the group agrees on.
Mosaic Moon is now running our own co-ops on our Ravelry forum as well as the Hyena Cart Co-ops Forum.
There is also a continually-updated list of other groups/co-ops ordering our yarns/fibers Here.
Drop us a line if you need any help finding what you need. :)
