What you need:
Large picture frame
Woodstain
Sandpaper
Hanging wire
Clothespins
Hot glue gun
Coffee
Let's start by staining the clothespins; all you do for this is brew a pot of coffee and let your clothespins soak in it overnight.
Now you'll need your picture frame.
And your sandpaper.. Now you can start sanding down spots of the frame. Don't worry about it being perfect, it's supposed to look old and dingy.
Grab your wood stain and a paper towel. Start blotting it on over some of the sanded areas (again, doesn't have to be perfect).
Now let it dry a little and wipe the whole frame down with a damp rag.
After the frame has dried, turn it over and begin hot gluing hanging wire at random angles across the frame.
Using clothespins, attatch your favorite pictures to the wires wherever you want them.
Hang your completed masterpiece in a place where everyone can see your amazing handiwork!
