Rachel: Giving someone you don't know, who has expressed an interest
in manufacturing your jewelry overseas, sketches and drawings of your
designs is almost certainly not a good idea.
Anyone who has lived overseas can tell you that having another
person/company copy your designs is a MAJOR problem.
Also, you can talk all the legal mumbo jumbo you want to--contracts,
copyrights, etc., but its a lot easier said than done--after all,
how do you sue someone in Thailand or China?
My advice--proceed with caution! If this person is legit, ask for
references here in the States for other artists they've worked doing
the same thing their suggesting they could do with you . . .
