I make perhaps 25-30 a year. It's still just a hobby. I don't see it becoming a full-fledged business, as I feel that the key to my limited success is that it's all done by hand, and in order to substantially increase the income, I'd have to either:
A. mass-produce using generic templates and a sewing machine, which would wipe out the custom, handcrafted aspect
or
B. charge a fortune for each piece, which would probably be appropriate in terms of the time involved, but not for the inherent value
I typically charge $65 for an Avenger or reinforced pancake, $50 for a pancake or simple pouch holster, $125 for a shoulder rig, $25 for a single mag pouch and $30 for a double.
