While it's true there is less of a market for hand quilting now due to machine quilting, it seems to me that you just have to find your market.
Last time I checked here in Sarasota one of our local fabric/quilt stores was charging $1.00 a yard for hand quilting. Small church groups in Pa. are doing the same thing for .35 - .50 a yard.
If you buy anything from Keepsake Quilting they have a membership plan that includes running an ad online on their website. That may be a possibility.
Where else could you place an ad online? Craigslist?
Best wishes, Sarah
