I would like to make the Harmony in Red by Matisse to look like a painting. I have the poster but I'm wondering which liquid material to use. I know there is something called Mod Podge and another one called Liquitex Matte Gel. I was wondering if you guys know these products or what else can you recommend. I would like it to look like the poster has brush strokes like a real painting. Any ideas? Suggestions?
