the boys that made these were 6 & 7 years old. Pick a theme, find illustrations/scrapbook paper, magazines, cut out, paint birdhouse close to theme color, let dry, then use Mod Podge on the back of image, apply to birdhouse, again apply Mod Podge on top…when all images are on, paint 2 coats of Mod Podge, let dry…get a big, long drill, with a big, long screw attached, drill through the back of the house by entering through the hole. We put ours right into trees. A good coat of Varnish exterior will make the images last a little longer, but should stay as is, for about a year.
When dulled by weather & time, redo!
