There is a glimmer of hope in my household. My nephews and niece have been visiting for several weeks and my niece decided she wanted to build a model!
I had an old Matchbox 1/72 F-5A and we started on it. I just guided her along, and only did some building when it was a little beyond her. We made the F-5A prototype which was bare aluminum so we used automotive chrome paint. Model came out just fine and she has something she built herself to put in her room.
My nephews want to build models but their mother won't let them build on the kitchen table (which is the only place) because she says the table is for food and not chemicals.
I also wargame and I have some old 20mm Civil War figs that I painted and based a long time ago. The boys spend time with these and they were wargaming with some local kids using their imagination and their own rules. Traditional wargaming is also a hobby with an aging membership.
Another thing I do is give the kids completed models for birthdays and Christmas. This helps them gain a little interest in the hobby.
Basically I try to get them interested in modeling in a fun way. I think if we over-strongly encourage kids to get into it they will just go find the computer or gamecube.
Cheers,
Get young people into the hobby but make it fun!!
