I have a collection of about 300 impressions taken from carved boxwood moulds, that I got a few years ago from a framer who retired. Some of the impressions are rather poor, with air bubbles and other defects but the vast majority are very crisp and finely detailed.
With these it is possible to make hard flat moulds which can used to cast compo or two part epoxy putty ornament which can be applied to frames. It's not particularly straight forward or easy to make the hard moulds but none the less it does give the potential to do so.
We have about 50 patterns made into moulds already, who knows if we ever get round to making any more soon. I do need to make some very thin ribbon and stick ornament for one job, the impressions I have of this ornament style can be seen in the middle photo, varying in width from 3 to 6mm.
