All I did was spend an afternoon with my camera to take pictures of things that look like letters (fences, scroll work, ladders, etc), then my husband used Photoshop to crop them and make them all black and white. I cut them out and put them in a frame from Ikea. You can also use individual frames (standby for future pictures).
It was simple and thoughtful. Here is the one we made for my in-laws all wrapped up and waiting for them! I stubbed my toe on it about 3-4 times while fluttering around the house getting ready for Christmas, but all I could do was laugh (it hurt really bad too).
