Get a cheap screen printing frame holder thing off the Internet, order some ink and a squeegee, I used to burn my own screens but now there are places that will burn your art and mail it to you pretty quickly and it’s way better, easier, faster than trying to get an exposure perfect on your own. I do t shirts but it’s pretty simple. YouTube a video on how to technique and you’ll be golden
I should really get a laser printer but my need for 11x17 capacity kind of limits options. To be fair though, my brother small business type inkjet printer does pretty well! Ink costs suck but I don’t want to commit seppuku after using it.
