In response to all the questions about dice bags in my #needlepointmonday post, I figured I'd offer a short post on this aspect of nerd culture.
A dice bag is exactly what it sounds like. It is a bag that holds dice! Tabletop games like Dungeons & Dragons (D&D) or miniature war games require an obscene number of dice of varying shapes. In Warhammer 40k, a player may need to roll more than 20 6-sided dice at a time. In D&D players will use dice with multiple sides, up to 100-sided dice.
With multiple players and each individual having their own unique sets of dice, a dice bag is a bit of gamer bling that can't be done without, especially when they've shelled out money for custom dice they don't want to lose.
In D&D Culture, your first dice bag is usually a Crown Royal bag. It doesn't matter if you're underage or don't drink... whether it is an older sibling who provides the bag or if it comes from elsewhere. It is long-standing tradition. I have no idea why.
There is a huge market for custom dice bags. It is a way for tabletop gamers to show off their "gamer cred," their favorite fandom, or something unique about themselves. While I don't often break out the sewing machine, I've had a huge push for them lately, since I made some for my husband to give away. I imagine you'll see some more dice bags from me in the near future as I work through the commissions I said I wasn't going to take. ;-)
