if you live in an area with upscale neighborhoods you have an upscale market.
then you have to figure out a way to get your name known in this market. look to see if they have art festivals, craft fairs, boutique shops, main street festivals, etc.
i started by working with local boutiques and the local art festival. then i donated a few quilts for charity auctions at 3 local country clubs.
once my name got out there i was able to switch over to mainly commissioned worked.
then last year i won an art competition which open a lot of doors for me - it was an invitational art festival and only 2 fiber artists won.
when i started i figure out what i thought people would be willing to pay out at an art festival and i created works that i would be willing to sell at that price.
when i'm working a festival i keep my piece in the range of $50-$450 - in my area i know i can move this product.
the bigger more expensive pieces are done by commission and i typically have 3 meetings with the client before i begin and i require 50% payment up front and 50% on delivery.
