I've looked into purchasing materials for this and I have some bad news. Screen printing isI can't afford to pay for hi-quality printing right now.I'm still going to try to make hoodies, but if I can make them I will be unable to do more complex designs like Luna or Rainbow Dash, and the quality of the cutie marks won't be quite as good. They'll sell for cheaper, but what I can do with them will be limited.You'll see an example of "lower quality" when I make one for myself, so stay tuned.The whole set of pony hoodies I designed. * Ellis1342 has been making designs too, and hers are a bit more detailed.I am actually looking into making these now!! I have a basic process figured out, and just need to try it out to see how well it works.I may open up a business on the matter, actually making & selling these things. If I do so, here's the few things I know for sure:- These are going to be custom made on request. The good news is this means that you can hand me a design or a pony and I can make it, regardless of who it is or the design itself. The bad news is this means that I'll have to buy dyes/inks seperately for each hoodie, so the price will be a little more than if I could mass produce.- Ponies like Rainbow Dash are going to cost more. The only way I'm going to be able to do that kind of thing is through screen printing or steam press, not dye, which means it's going to cost more for me to do.- I need hi res images of the pony's cutie marks to do this! So I would love if someone could point me to a place I can get 'em.
