if you make something fairly decent, and price it reasonably, demand may well exceed production capacity during the season.
thusly, order times fall behind and people are then "waiting".
to reduce the waiting, one can reduce the demand load by raising prices. and that will work.
or, one can work more hours, and that ruins your life and your real job. it is not sustainable over time.
or, one can figure out how to make more product in less time. there are limits to that in the real world, and it can involve vast investments of capital in equipment that may, or may not, pay off. manufacturers work on that equation All the time.
or, one can outsource production to people who do not care squat about quality and things that have your name on them. that gets old pretty fast too.
or, one can work until demand exhausts inventory and stop selling for the year. and that will work.
or, one can work steadily, polish production methodology, keep prices reasonable, and generally figure out that in limited amounts, "waiting" not only costs the manufacturer almost Nothing, but actually Increases the value of his labor. and that will work.
so you see, in a cottage industry scenario, there are several workable choices.
i vastly prefer to sell from a position of having stock. it's much more fun to sell from a substantial quantity of already built gear. i do not enjoy being behind. but once the inventory wears off ... wait happens.
more : i remain unresolved as to the morality of raising prices beyond what i think the product is worth. i know as a capitalist, i should let the market make that determination, and i am fine with that. but unfortunately, i was raised in a more confused environment, and so crossed signals can obscure the serene beauty of economic purity.
