because the old paint was already pretty rough-looking, i didn't have to do much to make it look weathered. i just sanded off the loose paint (because who knows if it was lead paint, and i can't promise that jake wouldn't eat a paint chip off the ground), caulked the window panes that had lost their glaze to hold them in place, and then i scrubbed the years of dirt off the window!
if you aren't tearing down a garage and just so happen to have an old window lying around, try the antique shops and yard sales near you!
i printed 4x6 pictures from snapfish for free (when you sign up with a new email address!), so i carefully taped them in each window pane. and since the window was hung kind of high above the fireplace, i added some twine and hung family pictures beneath the new wall decoration.
