You are looking at a minimum of 80 hours of work for the leaves only--that's 2 weeks of skilled labor, plus you have your piecing and quilting on top of that. For your quality of work--which is absolutely gorgeous--I would consider 1,200 for labor only and add the cost of materials on top of that at a minimum. It is worth more than that--I have seen quilts with labor like this sold at our quilt show for 2,000--which for your quality of work is well worth it. Don't sell yourself short. You have built your reputation and need to be paid for it. Love your quilts!
