Improvised frames and tarps (with sag!) for AFVs

Chris Kemp has posted a brief but novel explanation on his blog about creating canvases/tarps and then getting the sag right when they are on frames. I hadn’t thought of getting sag using something like thin/flexible wire…I use rigid things like bulldog clips or clothespegs. Those methods of mine won’t really work for this sort of thing…this copper wire idea is simple and practical, and I should have some floating around the house or the shed somewhere.

Of course, I’ve always had pliers at the hobby table – they are necessary for when I’m working with wargaming figures made of various white metals or lead/pewter compounds (none of which are WWII, so you don’t see them here).

Does anyone else have any cool ways for improvising tarps/canvases when arranged on the frames of AFVs and other vehicles? Suggest them in the Comments!
