I have an old calendar block that had a Christmas image glued onto the top of it, so I removed it and am making some photo blocks to use as photo birthday months for the family.
Paint all the sides with your chosen colour - I mixed pyrrole red, bunt umber and a tiny amount of black.
Dip, drip and dry four of the sides with a couple of different watery washes to create some texture.
Stamp a large image straight onto another side using black archival ink.
Adhere the photos to the two blank squares and leave them to fully dry.
