Thank you for the help!!

Those are pretty interesting ideas
It was for two gallery shows which unfortunately had started a few weeks ago and will already end this Sunday.
The thing about my fabrics is, the edges of each one are jagged

(I had trouble weaving them straight), so I had to hide the edges. What I did was take mat board cut to 6 x 6 and then i placed the fabric on top, folding the edges under... behind the matboard. I stretched it from the back ---instead of stapling, like in your suggestion, I just sewed strings at one edge to the other edge, stretching it taut as I went along... This way, it didn't damage the fabric.
They all hang separately on the wall... It's kind of a series

I haven't even visited my exhibitions yet...so I don't know how they hung them on the wall. I only tied string across the back of board so it would hang from a tack on the wall, but I'm not sure if it will lay flat on the wall like that...
The other series I had are prints, and the fabric is fairly light and fine and I just mounted it on mat board using mounting tape. Then I cut a square with a square inside (a frame) of mat board and put it on top, to cover the edges of the fabric... using more mounting tape. The nice mounting tape has styrofoam sandwiched between two tapes, so it gave a nice 3-dimensional quality
Now I realise mat board is not too difficult to cut
In fact I'd tried to cut it in one swipe in the beginning, so no wonder I almost gave myself arthritis

This time I went over the incision about 3x and the slice was nice
I'll post the last set of fabrics (my paper ones) after this Sunday. I sewed the fabrics on to stiff paper and taped it to foamcore, applying another layer of foamcore on top, for framing each fabric and yarn sample. This one was harder to cut cleanly... because of the styrofoam in the foamcore... a little messy... (Foam core is just two glossy papers sandwiching about half-a-cm of styrofoam)
