@Thenomain There's real truth in that. Suddenly popularity can crush a tiny company working by the skin of their teeth on the margins fast.
When you have space and skilled personnel who can produce X per year, just getting $$$$$ more for materials isn't going to get you space to make more faster, or more people who know what they're doing. This gets all the more true the larger the items you make are, or how specific the skillset is to produce the desired item. Some things, the money can help with. Others, unless you're really damned good at allocating it well, will end up eating up money you never expected to be spending.
This actually happens a lot with tiny businesses.
It gets worse when you're working on a very thin profit margin, since the impulse is to reinvest. The above is how I nearly ended up bankrupt due to someone else's clerical error on a business that was well-received and seemed destined to keep growing somewhat faster than I could have predicted. The error was just big enough to prevent the purchases that would have allowed that business to keep going with materials needed for production, and the over all loss just enough to put me within $200 or so of bankruptcy that year.
It sucks, and it sucks hard, and money absolutely should be returned to anybody who put a deposit down for companies that operate with a pre-payment/deposit like this, but it is a thing that happens more than one might think.
'You seem to be doing really well with this!' is not always something people plan for the right way, or with enough of a buffer in case of emergency. (For instance, I'd picked up a pile of materials to keep going... but the error caused not just the inability to turn a profit, but to ensure I couldn't get the other half of the stuff req'd to actually produce anything from that point forward. I did dyework; I had and have a pile of things to be dyed. That's hard to do without the required dyes and processing chemicals, however, which is $2k I simply haven't had handy since.)
