The latest update - the surface texturing. I have used a mixture of uPVA glue, textured paste (artists use it to thicken and add body to acrylic paints), fine sand and ready mixed filler to paint on a protective and textured coating to the model. I find that this texturing gives the model a better surface finish, adding interest to the plain card detail as well as giving the card a stronger and longer lasting surface finish.
I have used a large, soft bristled brush and watered-down the mix with water to which I have added a tiny drop of washing-up liquid. The plain white-washed base also helps with painting.
The next couple of steps will show how this simple card building was painted.
