Most Gessoes are white, however, if you want a particular colour, mix a few drops of acrylic paint into the gesso to change the colour.
Leave the gesso to dry for another 24 hours. If you can still see the cardboard under the gesso, wait another 24 hours and apply a third coat.
Try not to push down too hard, otherwise, you risk damaging the surface of the cardboard.
Watercolours don’t tend to work well on cardboard because they require water. Choose acrylic or oil paints instead.
Purchase spray paints from a hardware store or an art supplies store.
If you don’t have an old sheet, use a tarpaulin or sheets of newspaper instead.
Give the can a 10 second shake every hour to help the paint flow easily from the nozzle.
Try making zig-zags, polka dots, and swirls. Be creative! Don’t spray a section of cardboard more than twice as this can oversaturate the cardboard and make it warp.
Consider using a different colour to create contrast in your painting. If you want to do a third or fourth coat of paint, let the painting dry for 2 hours before applying each additional coat.
If you need inspiration, find a landscape photo you like and try to recreate it. Include interesting animals, people, or plants in your picture to make it unique. Let your imagination run wild!
Make sure that the workspace is protected by plenty of newspaper as finger painting can be messy.
For a more realistic look, paint the sky first, and then the sea.
Purchase stamps from a craft store.
