Luckily I just happen to have all that equipment at hand

and will be tinkering around this afternoon
Cheers.
edit- been having a play, can't really get anything better or too different from the AP/GW stuff, I find the AP stuff pretty near perfect anyway. At some point I'll get some Liquitex inks and use them as the pigment.
I used Liquitex Ultra-matt, which isn't ultramatt at all just more matt than the regular.
And Winsor & Newton Flow Improver (warning this stuff is uber powerful so read the label)
and if you are in the UK you can get Talc from ebay, search for Magnesium Silicate - I ordered 600g of the stuff and it' gonna last me a lifetime - and I use tons of the stuff.
