These are very pretty and will easily sell. Not less than $40- I would charge 45-52 and I don't live in Northern Cali. You have materials AND time into these. I would add some upgraded buttons too. I am now a toggle button hunter as I like the way they look on the Bow Tuck- was my hubby's suggestion- said they would add class. Why do we as quilters, seamstresses, etc focus on "how low can we go?" You aren't just the sewer but the color coordinator, shopper, and quilter. And you either drove to buy the fabrics and/or you spent time putting the fabrics together. Each component has a price tag.
It is not just the time we sit and sew. Make up some nice tags to attach to the bags with a fancy ribbon. Good luck!
