If it's horizontal, then the sleeve/rod would work - remember to leave room for the rod in the sleeve or you'll get a bulge on the front.
Velcro will also work - machine stitch the fuzzy side to cotton twill tape, or to a doubled length of unbleached muslin, and hand stitch the twill or muslin to the textile.
If it's vertical you might need to hand stitch a couple of vertical tapes say 1/3 in from each side, using a zig-zag stitch, to help distribute weight or,
A lining hand stitched to the edges helps distribute weight too.
If you do the tapes or lining, find a place to hang the textile and pin/stitch while it's hanging - otherwise it's hard to get it to hang straight.
John's Lee Valley clips are pretty, but probably won't distribute the weight evenly - you could get sags. Don't know how strong the spring is- they might squash too much. Padding with ethafoam/fabric liners might help there.
Have fun!
