I've started reading a pretty cool blog site called www.larping.org. His weekly round-up has a lot of interesting items related to all avenues of LARP. There are also a few resource sections like lists of stores, etc. I have it bookmarked and check it routinely.
I just came across larpwriter.com. It is a site that enables would be LARP writers to create and organize their characters, NPCs, factions, etc, all online. It even outputs to PDF for you.. What's more, it's free and works off of donation only. I have started to setup my first LARP in larpwriter, and so far, I'm really impressed.
for prop buidling resources:
scrapyard, all kinds of portal building equipment ect.
DIY stores, latex paint and all the other stuff they have and we abuse for whatever its not ment for.
furniture stores, the ones where they do the fabric as wel, for good foam and if your lucky they have leather as well.
second hand store's are a goldmine if you visit them regiuarly
This is mainly for NERO larp but can be adjusted for similar larps:
FL-414 - Best for One handed swords use with McMaster Carr foam part
number NOT for 2 handed weapons(it will snap)
FL-505 - Best for heavier one handed swords or one handed shortswords
NOT for 2 handed weapons(it will snap)
FL-602 - Use this for 2 handed swords. It is not good for one handed
swords. It doesn't have enough flex at that length and although it's
light for a 2 handed sword it's of comparable weight to a PVC
Size 1-3 Microfiber tights with a toe. - Walmart is the best
cost/durability. Three packs are cheapest, but you usually have to get
three different colors for that. Remember to not get ones without toes
or with multiple toes.
Clear latex wears
FL414 $8.29 Product ID 007017 .414 kitespar for one handed swords
FL-602-60 $14.99 Product ID 007037 .602 Kitespar for 2 Handed swords
Shipping is about 10 bucks for 3 cores.
Gorilla Tape - Heavier and more expensive than normal 3m or Duck brand
duct tape. Better for holding things together but I would not
reccomend it for weapons. Buy it at Home Depot
Gaffers Tape - Available in lighting supply stores, similar to duct
tape but does not leave as much of a residue when removed.
Recommended for holding covers onto weapons. Very suseptable to cold.
lt will freeze and fall off. http://www.tapemonster.com/
An interesting Larp Magazine is coming out in Fall of 2013 - www.facebook.com/LiveActionMag (it doesn't have a real site yet, still working on that). Will promote all larp groups, businesses and larp articles. Might be good to like that page to keep up on what is happening.
