Here are this years cards I made. The gold one is a variety of gold paints and gelato with a frame also then painted gold; in the background of the frame is some metallic leaf stuck down and then the letters a pre-made plastic ones that I've added some paint to (which makes me wonder if we could print some letters like this on the 3d printer.....).
Then I added a bunch of buttons and embellishments also painted and waxed and glitter added to finish.
This one is a couple of paper artsy fresco paints and then some paint through a stencil; then I made a heart and letters using a silicone mold with some modelling paste and then I added some ink and wax to the heart to colour it. A quick swipe of gelato finishes the corners.
