Hi Jeff,
We successfully received the blankets and I have used them to construct a 1.8m by 1.8m practice room. We tested it last night with my wife going outside into the street. The flute/clarinet cannot be heard at all; soprano and alto sax are extremely faint and tenor was most obvious, but any ambient noise in the street covers the sound and people walking by didn’t even look up at the noise. We are very pleased with the results from a noise minimisation perspective. In terms of creating a room for practising and recording, I am also very happy. I can hear every minute wobble in my tone and I even heard a pad leak from my clarinet! Click 
VB70G. Sound Blankets Producers Choice- White-Black. Size 80×80 with Grommets. Single.
I have put up some photos on my Facebook page, and I’ve already had enquiries from friends, so hopefully you will get a few more orders from Australia.
Thank you for the follow-up and best wishes to you and yours.
Regards,
