Hi, Scott!
Some random guy on the internet once said, "If you're still breathing, it's not too late to try something new." So there are important things on the internet aside from cat videos.
By the way, I'm Jeff and I'm one of the New Player Reps around here. "Silly" and "dumb" questions are my favorite, so if you have any, fire at will.
As for where to go, we have Facebook groups dedicated to crafting garb, props, and weapons:
Knight Realms Official Costuming Community
Larpers Costumer Forum
One of them is unofficial; you have two guesses.
Since we understand the difficulty sometimes in leaping right into the action without knowing anyone, there is also a board here on the forums for forging in-game connections before you arrive:
www.knightrealms.com/forum/character-ties-and-connections.html
Finally, there is another unofficial Facebook group for role-playing tips called LARP Role-Playing Tips (shameless plug, both because I created it and because I named it so brilliantly).
We're here to help if you need it.
-Jeff
