Thank you all Gents!
Well, Rob, for the bandoleer I spread the cyano with the tip of a toothpick until the paper becomes slightly translucent and hard; I think it gives to paper a very realistic appearance of the leather consistency; then I arrange it on the figure and fix it with some more cyano on the back side.
Actually I havo no problems in positioning ...
The real chevrons were made of fabric so I prefer to use the white glue that allows me to "sculpt" it for a little while, to give the proper shape and folds.
After fixing the paper chevron with some pure white glue I use a toothpick to spread some diluted white glue on the paper. It becomes quickly soft but the "sculpting" time is quite short because the wet paper tends to "disaggregate" if overmanipulated.
Hope it helps!
