This time I used Unibond for the PVA constiuent. I had a Box of Pollyfilla powder, but I used some pumice powder that was hanging about. It gives the mixture a slightly grey look.Talking of tinting. I routinely mix dry powder paint with ripple paint. You can get quite a lot in and the paint will absorb it. Some of my samples are at least 15years old and no signs of deterioration. You can get concentrated pigments in liquid form at your local DIY shed.
Anyhow I can't tell the finished result until the morning when it has had time to harden. I sprinkled some dry pumice on the wet surface and also some yellow and brown dry pigment. At the moment it looks, well errrrrr....intriquing.
*The leather effect is a piece of whatsit.
A couple of coats of manky brown (raw umber+dab of white) followed by well diluted black. Stipple and dab with a paper towel.Wax/wirewool and polish whe thoroughly dry. The 'orange peel' surface of the greyboard works in your favour here. Notice on the demo how I've left the black heavier in the corners. Nice touch. It doesn't really simulate leather, rather it simulates imitation leather.
One thing though. To use a waxed finish mount under glass can have wierd effects if you don't space the glass away.
For old faded velvet, get some mid-toned mountboard, red or green works best. If you can get an Ingrés paper, so much the better: It simulates the weave lines. Just splodge it with diluted black or dark brown in a random manner. It looks awful until it dries. When it's under glass the effect is quite uncanny (don't wax it).
