Using a multiplier of material costs to determine selling price seems to be only a way of belittling ones work. An artist does not charge based on cost of paint and canvas. I'm a writer and my payment is not dependant on cost of paper. Turning items is a little different, we do have material and tool cost. I'll agree to some extent one must factor those into final selling price. I generally start at 3X material cost then just 'gut' it from there to what I think the final product is, or might be, worth to a potential buyer based on artistic and creative value. I also make duck and other game calls. Some, with the same material cost, I don't think I should ask more than $10.00, others easily are in the $100.00 range. At the same time, we must take a businesslike approach. This spring I will be putting pens, and other items, into a consignment crafts store. They charge rent and a commission. I plan to add about a flat $5.00 to each item to help cover that cost. I'm in business for me, not for them.
