Batiks - How to stick them into a frame

[Again]

I have a couple of old batiks that I bought in a charity shop and want to put them into a new frame. I'm afraid that the type of glue I use will leak through and ruin them. Does anyone have any suggestions?

Ours is on the wall stapled to a plywood frame... you bend it round the outside and staple behind it. Bit like a canvas.

Not sure where you'd get that sort of frame from, ours came with the batik. Art shop? Google?

I think this is the sort of thing

Thanks Heathen. They are not very big though and I would obscure the signature if I stapled them around at the edges, because they are quite close to the edge of the canvas. I was thinking of putting them into a clear perspex/glass frame with white around the edges, one under the other in the same frame.

Would spraymount do? I don't think that it stains.
