Jennifer, You might go to a hardware or hobby store and ask for thin strips of brass. Maybe a quarter inch wide and pretty thin.
This may be flexibel enough but tough enough to do the job. How you hold it standing on its edge and maintaining a curve is another problem, but maybe you could get a chunk of beever board into which pins could be shoved to hold things in place. Perhaps push pins or drawing pins, the ones with long plastic heads, might work? Starting thoughts anyhow. /tom Fowle
