Begin by ascertaining what sort of camouflage pattern you will be using. Traditional camouflage is known as woodland camo. It features earthy colors such as brown, dark green, splashes of black and tan. Desert camouflage features light browns, sandy-colored hues and earthy yellows. City camo is a bold pattern featuring black, gray and white. Arctic camo is white and light gray. Simply pick out one or two colors from the camouflage print you are using for the bedding and paint the walls these colors. For example, two dark green walls and two light tan walls. Paint the opposite-facing walls the same color.
Use a pencil to draw large, uneven, interlocking shapes on the wall. Aim to make each piece of the camo pattern around 1.5 square feet, but keep it an uneven shape. Label each pattern with the letter of the color it will be painted, ensuring the same colors don't sit side-by-side. For example, when creating a woodland pattern, label the shapes "G" for green, "B" for brown, "Bl" for black and "T" for tan. Work across the wall painting each green piece first, allow to dry, then paint all the brown pieces. Continue until the wall is complete, allowing each color to dry before starting the next one.
This technique is similar to the faux marble technique but without the distinctive marble veins. For a woodland camouflage effect, paint the wall a base coat of light brown. Allow it to dry for 24 hours. Choose two muted green shades, one darker than the other. Mix one part paint with one part water and one part untinted glaze. Repeat with the other shade of green so you have glaze mixtures of slightly different colors. Apply each glaze color in alternating stripes approximately 1 foot long and 6 inches apart. Lightly rub a balled-up cloth in circular patterns over the glaze lines to smudge and blend the colors together.
Use a sponge painting technique to add texture to the walls without creating a distinctive camouflage print. Paint the walls with a light brown base coat and allow them to dry for 24 hours. Mix one part green paint with one part untinted glaze. Saturate a natural sponge in water, wring it out to remove excess water, then apply the green glaze mixture to the sponge with a paintbrush. Dab the sponge across the wall, reloading with green glaze as required.
