Thanks for the words R_Boba. Now my 2 cents and this is from experience. I started making my belts and charging just enough to basically cover the price of materials. I found out pretty quick that it consumes a TON of my time. If I were single, I could pump out 5 belts a week but since I am married with a son and another one due in a month, my time is precious.
I like to help the next guy out as much as I can but at some point I have to justify the effort. I will charge more on my next run of belts cause I can't do it for cost anymore. Note though that I will be up front about it. I'm not trying to get rich off of making belts, but the ends must justify the means.
I guess what I am saying is that whatever you charge, you will quickly find out if that price is a fair price. Honestly? If I had to paint a ROTJ pack again for money, I would be looking in the $200 to $300 price range.
