Actually, it looks slightly better against a white ground than free standing, which is why I considered a box frame. But even doing that is problematic....how to secure? Glue would show. I'd like it to float.
The wall fixings are too expensive. I have bought an Adjust-a-bail, to see how that might work, it is acrylic.
I would really prefer to stand it on something. Sob. I keep seeing images of tall bits of flat glass standing on wood blocks, with metal pieces which look like the wall ones - but I am blowed if I can find these vertical ones anywhere - and I am persistent, spending ages searching on line. Someone called Stephen Hall shows pieces displayed like this but his website does not work so I cannot find him to ask him!
Incidentally......have tried to upload a photo of it from Flickr. I copied and pasted the Flickr address between the image buttons. It is 400x300 only so I do not think it is a size issue. But it has not appeared. Anyone know what I am doing wrong? Here is the address if you want to see it:
