Then I put it off. For almost a year. Sure, I read tutorials and bought some black paper (which I never needed). What put me off for a while was getting an oval picture frame. Then I got a couple, and let them sit for another few months.
However, I finally decided to do it today. It was a lot easier than I imagined. I did it all using some glue, scissors and minimal skills on paint.net (a free program that you can download if you don't have Paintshop). It took very little time.
First I took pictures of Matt and I in front of a bright window. After that, I cropped them in an oval shape and edited the brightness/contrast until they looked like this:
You can use a paintbrush to make everything in the silhouette black.
I didn't take pictures of the next steps, but they are very simple. I printed the pictures to the size of the frame, cut the faces out, touched up the black with a black marker and glued to white paper.
My OCD side is twitching as I notice that I hung Matt slightly crooked. You can assure yourself that this will be remedied.
