A relative of mine is an artist - and she wants to integrate her designs/artwork onto articles of clothing and other fabric goods (like scarves) and sell them. What is a good way to find out if this will sell? How does one go about beginning such an inquiry?

Prototypes and tests. I have a friend who "invented" new sweats. Actually it was just an improved upscale _style_ for wealthy people who want to wear sweats and not look like they just left the gym. Anyway, she went to a local seamstress and made 6 prototypes and went to a trade show. She shared space with another vendor and came home with $60,000 in orders. She then knew she was on to something! Be creative, go to local stores, flea markets, trade shows or anyplace else that makes sense to test with just a few samples. Money talks! Good luck!
