Now that's what I call dedication!
How about putting that rockwool in the back of those prints you've already got on the wall? I assume that they're canvas stretched over baton frames. I might have to do that with the ones that I have now!
Well I figured I have put so much effort into this build that I may as well go that extra bit.

Its no hassle from my point of view and certianly not a cost one either as they are so cheap to make.
I have a friend that does upholstery
Guess I'll be inviting them around for a coffee! 
I'm rubbish at wrapping presents nevermind acoustic panels! lol
From the research I have done It just seems the correct thing to do and I'm quite excited about
experimenting and the results.
