Magnetic Rubiks Cube Question?

I recently found an article on Instructables.com by Gary Fixler on how to build a rubiks cube using magnets. the ida is awesome, and works great. I am going to be building three in the near future, and I was wondering, which stickers would be the best for it? I want them to be normal colors (yellow, white, orange, red, green, and blue) and be the normal rubiks cube size. for example, where could I find the ones displayed on the cube at youtube (search magnetic rubiks cube, click first link). All help is really appreciated!
