Um, okay, first I think you mean sued. Although sewing is a good alternative if you want a human attached to fabric.
Secondly, unless volt180 is breaking copyright laws - which I seriously doubt he is - there is no reason to sue. Plus, as there probably is no breaking of copyright, a court would immediately reject the case for a) not being illegal, and

having insufficient evidence to sue for infringement. Plus, aren't we all technically infringing on the copyright of Halo by recreating weapons and armor?
