Start by cleaning up the birdhouse, then give it a good sanding to prepare it for painting. Make sure to remove any dust and particles. The cleaner the house is....the better the surface will be for the paint to adhere to. Use an old box as a work station to control possible over spray.
I love using "Krylon" indoor/outdoor paints. It coats well and is true to color. It also has the lowest amount of "scent" than the other spray paints. What little it has, seems to disappear fairly quickly. I found that spraying the lightest colors first, seems to work best. Don't forget to let the piece dry between coatings.
After you paint it, then just add some ribbon, a faux plant spray or two. To add snow, then place some Plaid texture paint where ever you think snow would look good. If you want to give the faux snow some bling, add a small amount of glitter to the paint and mix it. It gives the snow some sparkle that reflects light to add more fun to your birdhouse.
Let the texture paint dry according to the manufacturers direction. To protect it, you can spray it with a sealer or Krylon's Crystal Clear Acrylic. There you have it.
A simple and fun craft project that makes an old bird house new again. With a few adjustments, this can be an easy kids craft project or an upcycled project.
