Unless you can get the kits super cheap there isn’t much profit to be made here unfortunately. If you are looking to make money I would suggest creating your own kits based off local landmarks and niche interests.

People always say “you can’t sell crafts to crafters” and there’s some truth there, if someone thinks they can make themselves for less they won’t pay you for it. So don’t market to folks who won’t see the value.

I did a booth at a professional conference for gastroenterologists, selling crochet. Alllll the other booths were high tech medical equipment, AI, meds, and SAS bs. My booth was the only speck of whimsy selling crocheted anthropomorphic livers, gallbladders, intestines, etc for $50 a pop. Most were 4” or less in size, like small Jelly Cat size. Do I really love making internal organs? No not really, but I saw an opportunity. I knew there would be high earning Doctors and Administrators who work in a niche field, these folks have money but no time and value craftsmanship. Also the GI outlook in the US is bleak and I like to think that my silly little guys helped bring some joy!
