That's an awesome-looking space - everything from the outside doors (totally worth it) to the bold colours and artwork.

Regarding the fabric, the important thing isn't the thickness (a foil backing on rockwool makes an audible difference), but whether air can pass through it easily, or not. So, thin bedsheets (which are tightly woven) would definitely lessen the absorption of the panel, but a thicker fabric with a less tight weave would be fine. Hence the breath test - where you really can tell a huge difference between something you can easily breathe through, or the sort of thing that could be pressed over someone's mouth and nose in a crime movie!

But as fabulous as it all looks, the inspiration factor probably far outweighs any slight differences in NRC performance.
