i had the same problem when i first done a craft fair so many people were selling their
jewellery and hand mades so we were all in competition with each other, i decided that the only way to make money was to sell
small items at a pound each, such as mobile charms, keyrings and
small earrings, this worked for me and i still do it now.
The highest resolution projector in the model J goes down to 50 microns and while it has a
smaller working area than the others, it is capable of producing the finest detail on such
items as filigree type
jewellery.
