What Packs will you combine with Crystal Creations?

I already have a shop that sells crystals, maybe I will update it to include metals too. It's designed to look a bit like a jewelry store, on a lot with other shops as well, but I'm thinking of building it on it's own separate lot now that it's more useful. Would have been nice if sims could order certain designs be made for them if they provided the stones and the metals. I'll probably have more ideas once I know more about how the pack works and what's possible to do with them.
