RE: Covering ???
As in Digital Camo like the new army uniforms?
That would be neat, unfortunately all coverings come in 1 shade of color only, they are not very detailed unfortunately due to manufacturing costs to deal with all the different colors and patterns.
I don't think I would like that idea a whole lot to advocate for it. It would be a lot of work cutting out a 2x2 cm square and pasting on every piece individually using a pattern of about 3-4 colors. Alot of work...
