Step 1: Materials
A rubik's cube (or other cube)
Mod Podge or other glue and sealer
Pencil and ruler
Step 2: Getting Started
To get started choose 6 images that you would like put on your cube. I chose 5 characters from Gears of War and the Gears logo. I initially went to the local comic book store with the thought that I would pick up a few comics and cut panels out to use. This will work, but doesn't allow you to manipulate the colors. it also adds a little to the cost of the project. Instead I went online and found the images that I wanted to use and downloaded them.
I opened them in photoshop to play with the color a little. Once the image is open in photoshop go to Image>Adjustments>Hue/Saturation
Make sure preview and colorize are checked. At this point play with the hue, saturation, and lightness until you get the color that you want.
Next you need to crop the image into a square. Again go to Image>Canvas Size
Here I adjusted the image to be around 8 inches by 8 inches. This image was then adjusted by going to Image>Image Size
I adjusted the cropped image to 2 inches by 2 inches. You may need to adjust this a little to compensate for the size of your cube. My cube measured 2.25 inches. These images were added to a word document and then printed.
Step 3: Making the Cut
Don't cut them into the smaller squares yet as it can be a little difficult to keep them properly oriented.
Next you need to peel all of the stickers off of your old cube. If there is any residue left you can clean it off with a wet cloth or alcohol.
Step 4: Putting It All Together
I started with the logo first. I cut it into the 9 squares and laid it out. I then used a brush to put the glue on a few of the squares at a time. Be careful not to use too much glue as it can run into the cube hindering free movement. I used a second dry brush to mop up any excess glue.
Glue the squares down in the proper orientation. Once the first side is complete, cut the next picture and repeat the steps until the remaining sides are done.
Let the cube dry following the recommendation of the glue you used.
Step 5: Sealing
Once allowed to dry have fun mixing up the cube and solving it.
