Sooner or later in your serious pursuit of a hobby the temptation to make money with it will arise. Money Imps are everywhere; witness the internet. Every second communication you receive is urging you to monetise what you do. All you’ll need to do is send the person who wrote it your money….
It can be less sordid than that. You might be asked to take up prostitution or drug dealing, and what could possibly go wrong there? Or it might be as simple as someone remarking that your hand-sewn mechanical intestines are really very authentic and you should offer them to other gut-lovers. They’ll snap them up, if snapping intestines is a thing.
I write from experience. I was very good at making leather soldier’s accoutrement in the 1990’s. Cartridge boxes, belts, canteens, food bags, etc. I did a steady little trade in these for re-enactors in the black powder hobby, both in my own metro area and interstate by post. I even went round as a drummer for the business on one holiday trip – a lesson in itself. People paid their bills with admirable promptitude and I was able to make a tidy little loss on my investment.
Loss? Loss of money, as the price they were willing to pay was that of the items demanded in American catalogs or by Indian sutlers. I was buying raw materials at Australian prices. When the sources of cheap leather dried up there was no profit at all in it. Add to this the costs of postage…
Also loss of time and enthusiasm. Sewing 20 cartridge boxes for your own re-enactment group is one thing – sewing the same number for others where there is no profit, quite another. Eventually I was blessed with an opportunity to hand the business over to someone else who had just lost their day job – I could get out honourably and they could try to carry on.
The same would be the case in every division of every hobby. As soon as it was converted into a commercial proposition – however sketchy – the thing would become a job. It would take on the form of a task rather than a pleasure and the time spent doing it would be robbed from the day, rather than adding to it. Far better to do nothing for gain, and spend the time doing it for fun.
