Using APP Epoch and AASPN_FramedMasks4_2.
I started with a blank 12 x 12 page, added the plain paper background from APP Epoch, added the framed mask and then several overlays and coloured stains from APP Epoch.
I re-coloured all of the stains within the mask template via - Edit -Fill - Colour and selected a colour to match the palette. I did the same with the splatter I added from the palette as well.
