Shihli made a good point in his request for 16 slot bags.   I have a few piles of Netherweave bolts (like ten) and a few piles of Arcane Dust just lying around inside my bank.

The mats ask for two [Netherweb Spider Silk] which can be picked up anytime your in Black Morass, or from the AH.  Send me three of them and a [Greater Planar Essence], and I'll send you back a [Imbued Netherweave Bag] which is 18-slot.   And yes, I won't lie, I'm asking for the third to make my own bags w/out having to find the Netherweb Spider's Silk.  I'm Lazy.  Sue me.

When you count Bank Slot's, I'm planning on making 4 bags for Pedran, and 6 bags for his Bank. This equated to roughly 720 Netherweave Cloth, 20 Arcane Dust, 10 Greater Planar Essence, and 20 Netherweb Spider Silk.

Total Mats are as Follows(in case you care):

• [Bolt of Imbued Netherweave] x4 (Total Netherweave Cloth = 72)
  • [Arcane Dust] x2
  • [Bolt of Netherweave] x3
    • [Netherweave Cloth] x6
• [Greater Planar Essence] x1
• [Netherweb Spider Silk] x2

On the flip-side, if you don't have the [Greater Planar Essence], I can just make you a 16-slot [Netherweave Bag] instead.  I have all the bolts I need (I think, depends on what orders I get), but I would still ask for one Netherweb Spider's Silk.  :D

Total Mats are as Follows(in case you care):

• [Bolt of Netherweave] x4 (Total Netherweave Cloth = 24)
• [Rune Thread] x1 (50silver from vendor)
