I sell close to 90% of all my work, the other 10% I give away as gifts. I too have people telling me my prices are to low (it's usually my paying customers), and a lot compliment me on the piece but don't want to part with their money. I have a set rate I charge per hour( actually calculate it per minute), plus charge for all wood used and add a set fee for shop supplies. You are always going to have people that think it's to much, these are the same people that would go to the store and buy something similar for less but also mass produced not handcrafted. When I tell a "customer" a price and they say its to much I don't sell it. Unless I know there is a little wiggle room in the price that still pays for supplies and most of my time.
This is my hobby not my Job, so I look at it like this- If I can sell most things I make to fund my hobby great, if not I will have lots of gifts for family. I enjoy woodworking/scrolling so I'm going keep doing it. Don't sell yourself short.
Get some of your stuff out there, word of mouth is the best advertisement you can get. I don't do shows all my sales are from word of mouth, and I have several repeat customers. I recently started a facebook page which also seemed to help spread the word about my "crafts". my page is Clayton's Wood Creations if you want to check it out. Hope my rambling helps out some.
