I sell printable escape room kits. Somebody buys a PDF, prints eight pages, hides four of them around the living room, and forty minutes later there is a kid running through the kitchen holding a paper key. Nothing ships. Nothing sits in my garage. Eleven months in, it brings in about 410 dollars a month, which is roughly 47 downloads at 8.75 each. Etsy takes a bite of every one of those, so about 7.50 of the 8.75 actually lands, and the number that reaches my bank is closer to 350.
The first two months I made seventeen dollars. Two sales, both in month two, and I checked the shop stats page most mornings like it owed me an explanation.
The first kit took six weeks of evenings. A haunted lighthouse, eleven puzzles, a cipher wheel, a logic grid, the whole ambitious mess. I built it in completely the wrong order and did not understand that until much later. I wrote every puzzle first and then tried to bend a story around them, so the finished thing read like a worksheet packet with a lighthouse on the cover. The cipher wheel had to be cut out with scissors and pinned together with a paper fastener, and it never once occurred to me that a six year old cannot cut a circle. A buyer told me that. She was kind about it.
Then the printing problems started, and those cost me real money. My first four sales all shipped with the same defect and I had no idea the defect existed. Home printers do not print to the edge of a page. There is a strip about a quarter inch wide on all four sides that the machine physically will not touch, and my puzzle grids ran right out to the edge because that looked good on my screen. So the last column of the grid came out clipped, which meant one letter of the final answer was missing, which meant the kit did not solve. Two of those four buyers wrote to me. One was polite and one was not, and both of them were completely right. I refunded both, which erased most of what I had made, and month three finished at zero.
The fix took one afternoon and it is not interesting at all. Everything now sits inside a half inch margin on every side. Page one of every kit carries a small square with a caption under it saying this square should measure two inches, and the instructions say to switch scaling off and print at one hundred percent. That second part turned out to matter more than the margin. Printer software loves to shrink a page to about ninety four percent so it fits, and I had one puzzle where the answer came from measuring a map with a ruler. A shrunk page produced a wrong answer with no way for the family to work out why. Two more refund requests came in on that one before I understood what was happening. The ruler puzzle is gone now and I no longer build anything that depends on physical size.
What actually made these sell was not the puzzles. It was putting the same detective on every page. Her name is Inspector Halloway, she is somewhere in her fifties, brown coat, chipped enamel badge, and she writes the case brief at the front of each kit and signs the answer key at the back. She is an AI generated character. She is not a real person and was never based on one, and I say that in plain words in the listing description, because I would rather have that conversation before the sale than after it. Before her, my shop looked like eleven unrelated PDFs from eleven different sellers. After her it looked like a series, and second and third orders from the same buyer started showing up. The production side of it is unglamorous. Pages get laid out in Google Slides, Halloway comes out of APOB AI, and the cheap inkjet behind me prints every kit before the listing goes live.
The order that changed the shape of this was fourteen copies at once. Month six, one Tuesday morning, 122 dollars and change from a single buyer, and I genuinely thought it was a mistake until she emailed. She teaches fifth grade in Ohio and wanted one copy for every teacher on her grade level team so nobody had to pass one file around and get sideways with the district about licensing. She asked me two things in that email. Did I have a version that did not drink an entire color cartridge, and could the reading level come down for a third grade group.
Both answers were no at the time. They are yes now. Every kit gets a second layout with thin lines, no filled backgrounds and no full page color, plus a wording pass that keeps the sentences short. That ink light layout outsells the party layout, which I did not see coming. Classroom sales are lumpy in a way party sales are not. Nothing for eleven days, then five orders in an afternoon because one teacher put a screenshot in a Facebook group with forty thousand members in it. I have no control over that and I have stopped pretending otherwise.
Here is the part that is genuinely tedious. Halloway has to appear in the same coat, with the badge on the same side, on every page of a nine page kit, and about one image in three gets thrown out. The coat shifts shade, the badge migrates to the other lapel, she turns up holding a magnifying glass she has never owned, or the face is simply not the same face. For one kit that is a couple of evenings of generating and rejecting before I have a set I can actually use. Batching helps. I do all of her poses for a kit in one sitting instead of a page at a time, because when I stop and pick it up two nights later the reject pile gets bigger.
A few other operational things that took me too long. Etsy caps a digital listing at five files, twenty megabytes each, and my color versions kept coming in over that until I learned to flatten the PDF before export. A bundle of all my kits at 29 dollars has sold twice in seven months and I keep it up mostly out of stubbornness. A Halloween party pack with three short kits instead of one long one did better in October than anything else I have made. And the one habit I will not skip again is printing the entire kit and playing it myself at the kitchen table with a pen, because that is where I find the two places where the instructions can be read two ways. Every kit I skipped that pass on came back to me as a message.
I have eleven kits listed. The 47 downloads a month are not spread evenly across them. A train mystery and the classroom version of the pirate one carry more than half, and two kits I personally like better than either of those have sold nine copies between them since March. October is the strongest month by a wide margin, spring birthday season is second, and August is a graveyard. I started at 4.50 a kit and moved to 8.75 in month seven, and the sales count did not drop at all, which told me something uncomfortable about what 4.50 was signalling.
A kit takes me eight or nine evenings now instead of six weeks. Eleven months to reach 410 dollars a month is slow by most standards I know of, and I am fine with that. The work finishes when it finishes, nothing is waiting on me at seven in the morning, and Inspector Halloway keeps turning up on every page while I sit here trying to work out what she investigates next.
