Every once in a while I try to get Mike and Christian over for a Warhammer hobby night, to work on some models, brainstorm and BS.
Here's what you need to do.
1. Invite people-
Make sure to tell them when it starts and when it will end so they know when show up and when to leave. I called up the regulars and I decided to invite a stranger: Scott from the Bay Hammer blog.
2. Get food-
People like to eat and drink. Tell them not to eat before they come over, if there is food there is no reason for them to leave early or show up late.
3. Set up a work place.
A table with chairs and good lighting, paper towels water cups for cleaning brushes some tiles for painting and some tools.
4. Set the mood.
I put on the Soundtrack from Dawn of War II, good background noise.
5. Bask in the glory.
Pretend to act humble when everyone tells you how great everything was and how much fun they had.
I had a good time and it was good to have everyone together talking about Warhammer stuff.
You should give it a try sometime.
