I love this-- use ANY canvas, apply stickers, decal, etc., and spray paint. Remove Decals; hang white lights behind it.
Take something you really love, a letter, envelope, photograph, a ticket stub... anything - to a printing place like Kinkos and have them blow it up for you to hang as art. An old recipe from your Grandma would be great for the kitchen. What a fabulous idea!
Keep this in mind if you start seeing lots of spiders around your place. Natural spider killer or preventer... take one cup of vingar, one cup of pepper, a teaspoon of oil and liquid soap. Put it into a spray bottle and spray along the outside of your outside door and along windows; refresh after it rains.
