mugs & pricing

Started making these mugs because a customer who has arthritic hands wanted longer handles.  I was making shorter, rounder mugs before. Although the taller mugs look bigger they actually hold the same amount since they're somewhat convex in shape.                                I've been aware for some time that my prices are low.  Recently I came across a formula that explained how a seller might price work based on labor and material costs.  Using this formula, I came up with a price of $52.00.... for one mug.  Well, maybe I'll raise the price by a dollar or two.
