I was asked for some explanation of what I meant by 'sculpting with paper' when I described how I made my recently-posted Werewolf's torn pants cuffs. It's basically using a rough, permeable paper as scaffolding to soak with superglue that can be filed to a desired surface texture once filed.
Here, I'm bashing the Indy line's Marion Ravenwood with a RoC Cover Girl to give her some proper hip and knee articulation. I've scrounged up a Discover magazine subscription postcard found generously inserted loosely between the pages. It's similar to a kids kid's construction paper, and that should be just as useful. It's key that your paper can't have a coating on either side that would prevent the superglue permeating into the it.
I've cut a piece off the postcard a tax longer and wider than needed, to account for warping around her abdomen. I bent, folded, warped, and spindles the paper a bit so it'll be easier to conform to her and look like fabric. I've glued one end to CG's back and glued it down as I wrapped it around, ensuring the paper lays down with some natural-looking clothing folds. I want the straight edge at bottom, to become her shirt's bottom hemline.
Once I got the paper in place, I trimmed any excess hanging over the lower hemline (there was a tad bit in back), then laid down another layer of superglue to the paper's exterior. I tried to blackwash it so it'd be better-visible, but I fear my camera flash washed the wash away.
Once the exterior glue dried, I filed at it to get the smoother surface I wanted, and to emphasize the folds I want. This filing will sometimes expose inner paper where the glue didn't seep and it will look 'hairy'. Another glue application easily resolved this.
I use this technique fairly often as it's quick and easy compared to proper putty-sculpting. I've used it to tighten joints, cover screwholes, and fake up clothing; and probably a few other uses I've forgotten. Put it in your arsenal as I'm sure it'll be of use somewhere.
