Mounting large textile

[lehcar32]

I have no doubt this has been asked before but as the search function isn't working I can't find previous threads...

What's the best way to mount a Mexican Otomi embroidery on cotton? It measures 190 x 45 cm. The customer would like to see the wavy edge, so normally I'd stitch down to mountcard but obviously it won't come long enough. Is there a way to use the acid free foamcore - using pins perhaps? Or stitch onto another piece of stretched fabric? Conservation is important so I don't want to use MDF or adhesive anywhere. Any advice much appreciated!

I'm not sure if you can get proper acid free foamboard as large as that. Joining some pieces of conservation grade mountboard together and the cover the mountboard, an acid free cotton fabric might be a smart move. Another possibility would be to stretch an acid free cotton fabric on to a braced stretcher frame and sew the textile to the stretched cotton fabric and then frame it, with spacer to provide some clearance between the textile and the glazing. It might be easiest to glaze it using 4mm thick acrylic.

Use a raw (unprimed) piece of canvas or suitable fabric on stretcher bars and stitch it to that.

It would be lighter and flatter than a board and easier to stitch to.

I would make a stretch system from wood covered with nylon window screen material for strength and then cover it with an appropriate decorative fabric. The window screen material will give the fabric additional support. The textile can then be sewn onto the fabric/window screen combination.

Thanks for all the replies and advice. Stitching it onto stretched fabric sounds like the way forward. Just wondering, would it best to do it on a proper stretcher bars which can be re-tensioned (I usually order mine custom made from Harris Moore) or would a fixed batten job suffice?
