I read about another use for plastic wrap. This one is done by applying acrylic paint thickly to crumpled plastic wrap and letting the paint dry.
(I thought using thin rectangles for fence posts in the foreground of a picture would work well.)
Depending on your picture you may wish to use a blend of colours.
Another ideal could be to add some beads or other small items to the wet paint. Remember that you will probably want to use the rear of the paint as the good side so push the beads right down so you will be able to see them once you remove the plastic wrap.
You can use old paints or colours you do not particularly like to try out this idea.
My attempt was not too successful. I applied some of my old paints to the crumpled plastic wrap hoping for some wood-like texture. Once the surface of the paint was dry I tried to peel it off the plastic wrap.
It came off OK but it was only the surface of the paint that was dry. As the centre was still soft I left finger prints in the sections that were pulled off.
So I decided to leave it to dry fully. But then the plastic wrap was really stuck onto the paint and the crumpled areas were embedded into the dried paint. So no success this time either.
I think the trick is to judge the ‘dryness’ of the paint so that you can remove it from the wrap while it is firm enough not to dent from the pressure of your fingers but before it sets too much.
This may required a bit of trial and error to get it to work successfully. :-)
Maybe you will have more luck than I did with this technique. I think it would be really useful if you can get it to work!
