I belong to a group called The PHUCS, the PHoenix, United Crafting Society. We meet at each other's houses for pot luck and crafting. We also plan group field trips (art openings, roller derby, First Friday, museums, film screenings, etc) and support each person's endeavors. We all learn from and teach each other. Many of us were inspired by The Austin Craft Mafia, but are not affiliated with any mafia groups here in PHX.
If you're interested send me an email and I'll let you know next time we get together.
