How to attach fabric to inside out walls?

Hi, Sorry, I have searched for this everywhere and I'm sure it's very simple but..... once you have made a stud wall on the floor and have attached the gyprock (sheetrock, platerboard etc..) then lifted it into place, then filled it with insulation..... how do you attach the fabric?!! I mean without seeing the folds and staple marks. :oops: Bit of background..... making a small studio in my backyard based on John's 'small studio'. It is 6m x 3.2m and 2.5m high. Outer leaf is 6 inch core filled blocks. There are two windows, both are two double glaze windows, side by side. For the inner leaf I was going to copy John's 'small studio' and use inside out walls (2 layers of gyprock, stud wall and mineral wool, fabric) but can't find how to physically make them. Any advice would be great, even a link to a post would be appreciated... Thanks! Adam.

Build a 45 x 20mm frame and stretch the cloth over it and staple it to the back of the frame. It's best to make the frames on the wall then take them down, brace and add the cloth. Attach to the wall with thin brad nails that disappear behind the cloth.

Thanks John! Of course... makes perfect sense now.... :oops:

OK. I know I'm asking to be spoon feed here but unfortunately I'm no carpenter.... how do you then attach the slots to the slot walls? I'd be guessing they are nailed or screwed through the fabric frame into the studs but I can't see any screw or nail holes in any examples. Cheers, Adam.

One option is a French cleat... http://buildthisroom.com/french-cleat/ There are several other options...but this might best fit your situation.
