One of the advantages of burlap is that it shrinks well.... you can give it
a light spray of water after tacking it down to make it tight.

I have made some absorption modules (you know, rockwool and chicken
wire) and covered it with Dacron (to keep the rockwool particles
inside). Sounds good, looks godawful. I understand burlap is the
acoustic best fabric to dress it up with.
Unfortunately one can't get hold of that in the Netherlands. I know
this sounds strange but it's true; I'm at the end of a six weeks quest
and still: no burlap in any nice colour. Any foreign
postorder/internet companies that do coloured burlap? The weave must
be fairly course to allow sound to pass thru it without resistance.

Thank you for your time!

Felt looks good and works nice. You can get it cheaply at most fabric
stores
and it comes in many colors.
