I did not see a general forum area to put this in, so...

At this link http://www.fantasyflightgames.com/edge_minisite_sec.asp?eidm=269&esem=2 there is on the right side of the page an icon showing some squares with numbers in it. I'm assuming these have to do with the quantity of packs you need to buy to completely sleeve a game, but the different colors have me at a loss.

Is there a concise explanation of this system?

FFG colour code the card sizes, so the colours tell you which size of sleeves you need. In this case, 2 packs of yellow, 2 packs of green and 1 pack of orange sleeves.

Take a look at the Supplies section of the online store and view a few of the different sleeves... it should become clearer.

Edit: Note that green size doesn't necessarily have to be green in physical colour!

Which sleeve size do I use for my iPod so that the app is sleeved, too? =P
