This is just a simple sticker modification of a 4x4, to transform it into a 4x4 supercube in a clean and quick way.
Please note that this was not originally my idea. I saw it recently in a Spanish forum, where the author (MacrossDreams) made the mod by cutting out part of the original stickers.
I wanted to try it myself, but adding black sticker lines instead. And here is the result:4x4 Wrapped Up Cube
(since the extra lines look like wrapping the cube)

A very easy sticker mod, but quite effective. You just need some leftover black stickers, a xacto knife, and a bit of patience (... and a 4x4)
Cube looks nice, and it is a good, quick and nice alternative for a 4x4 supercube (imho, much better than a simple arrow cube)
Hope you like it
