This is a good weekend project since it takes time to dry in between steps. It's easy to start on a Saturday and finish (several) on Sunday. Even though these are all pretty much nerdy, you can do this with photos or any graphic you choose. My house just happens to be inhabited by video game players. If you have any questions about any step of the process, please comment and I will do my best to answer you!
Step 1: Materials Listing
1. A laser jet (This part is important. To see what the prints look like done in ink jet, please refer to the last step of this instructable. It's not pretty) print in the size of your choice (Staples near my house can do up to 2'x3' cheaply. I used 11"x11" images printed on 11"x17" paper and the prints cost about $1 each). PROTIP: Staples can change color photos/prints to grayscale for you. However, BEFORE going to Staples, open the image in an editing software (MS Paint will work) and choose the option to "flip horizontally" in order to avoid any words or pictures appearing backwards. If you don't, you'll be very, very sad (seriously, trust me on this one).
2. A piece of plywood cut to just over the dimensions of your print (these are 12"x12" panels. Home Depot will allow you to buy a large board and they will cut it into pieces in the store for you).
3. Acrylic Gel Medium (purchasable in the paint section of any craft store).
4. Mod Podge (purchasable in any craft store).
5. Light colored wood stain.
6. Stain rags (not pictured).
7. Foam brush (not pictured).
8. Paint brush (not pictured).
9. Picture hangers (they are pictured in that small package and are in the nail/screw section of Home Depot).
11. Small paint roller or ruler (optional)
