I have built several paper models, that are quite small. They are APC's, helicopters, tanks, and small footsoldiers. I'm using them to play a small wargame (in a 4' x 8' area). The problem I'm having is, the wind keeps pushing my models around. Even a fast movement by the table and soldier's will collapse and die. I've put pennies under and inside some of the larger models to weigh them down. I don't really like that option though. It doesn't work well for my soldiers, either, with thier small base. Can anyone give me thier thoughts on an inexpensive way of weighting my models (improvised, storebought, or otherwise)? Thanks.
