One thing a Guild can never be without is bags.
Our top Tailor Silvercalia, and my own Alt Tailors would love to keep the G bank stocked with cloth, such as Netherweve; found in Outland content, Frostweve; found in Wrath Content; and Embersilk; Found in MoP content.
As well, dusts and various enchanting mats are also required to make those wonderful large bags giving your WoW CHARACTERS MORE BAG SPACE for your personal banks and backpacks.
Leathers are also needed for other bag patterns as well, so when in doubt toss the extras in the G bank too so we can make bags for professions as well!
So please; keep the guild well stocked, or make donations with your leftovers!
Much Love, the GM! Crestwater, Moon Guard -US.
