buying a cricut?

so i just wanna match with my son like all the time, i just think it's sooo adorable.. buying just one customized shirt for me and one for him is pretty expensive.. so i had the idea to buy a cricut, and make my own shirts.. then i was like i can make them and sell them to other people too 🤔🤔🤔 there's actually a bunch of stuff that's super cute to make with a cricut that i'd be interested in trying.. for shirts, i wanna make stuff kinda like this.. but cricuts are kind of expensive so im scared to spend the money on it and not get my money's worth out of it.. you think people will buy stuff like this if i made it?? or anything customized in general??? is it a good investment??
