First of all, we believe that cut gems will stack. Currently, some JC's deliberatly hold low stocks of cut gems, others use mailboxes as storage (if only for expired auctions)
Secondly, we will be getting a 36 slot gem bag (requiring 3 dreamcloth to make).
I will be using my tailor to stockpile dreamcloth again when ever I log on to him. It won't be a high priority as established JC's already survive on their existing bags, and will get some bag space back simply from stacking. I do see some demand coming from:
- the top 4 or 5 gem sellers in your markets buying 4+ bags each,
- many 'guild/personal use' JC's will buy a bag as well
