Curious also, if social engineering wonder if I might be able to improve it.
edit: instructions missing the most important part of how to make 20x investment, which was arbitrarily calculated. Because sure, anybody can make a tshirt design, the question is where do you post it? And why not use a service like Redbubble or some other thing that will handle all the hard work and advertising instead?
The only useful part of the instructions are missing... where do you post it? Where does it get seen? Who do you sell it to? How much time are you going to spend on customer acquisition? This might be good for someone in highschool with lots of friends or some sales skills, but I'm not sure it's going to be worth anybody's time that is making more than minimum wage.
I'm not sure this poster has actually gone through this process. Pretty shoddy business plan, might make more money at mcdonalds seeing as there's no suggested way to sell. Because there is a massive difference between having a products in your hands and actually being able to sell that product. Anybody can do arts and crafts. This tells us nothing of how to actually sell it.
Like I said I will add some value to people who are looking at doing t-shirts, because it's not a bad idea to begin with, and they are high-margin and popular:
If you do decide to sell t-shirts and can't come up with a killer design, search for "public domain" art, slap it on a t-shirt and you have masterpieces from the greatest artists of all time on a t-shirt. There was recently also many many old books that became available in public domain, which means you can use any line. And it's completely legal. Just check the specific rules where you live. For US it's 70 years after the original artist died, for Canada is 50 years. It varies by country.
If you use a service like redbubble or threadless or society6 for example, you may only get a few dollars per shirt, but it's set and forget. If you set your tags well your stuff shows up in search, and the more people buy it the more visible it becomes. Literally the first public domain design I posted on redbubble started selling the very next day.
Passive income is great. I don't know if selling t-shirts by hand or to your friends or something (who knows what OP had in mind) is going to be worth your time. It's gonna take volume.
Also if you buy those cheap design transfer papers the design will crack up and wash off after a couple cycles, and you'll just get a bad reputation and no return business. Literally cheaper and less time-costly if you just order it already printed from alibaba or whoever, especially in china, if you really really don't wanna go the route of online marketplace.
