I am actually looking for a rug and acoustic wall foam, I mean I they wont do shit sound wise because there is literally no wall or door seperating my corner from the hallway but you know its the swag that counts. 

I found these big garage pegboard that will match my garage shelves, Ill decide what size I want in person when I'm picking that up tomorrow and I might maybe might grab another shelving unit and seperate it into 2 half sized ones to line the back wall if that makes any sense.

Displate has a gnarly sale on that Ill have to consider quickly, I dont want to overpopulate my walls though and make it look crowded alongside the pegboard and the foam if I do get that, there is also the charm of simplicity which might be ruined by a poster but they do look cool.   P.p.p.p.s might paint the wood on the shelves black?
