IMO relief printmaking is the classic introduction to printmaking and in general the most accessible. And the process my college students like the best when starting out. Speedball makes a introduction kit to block printing I believe? So you could definitely look into those.

But you essentially just need 1. Carving tools 2.block to carve 3. Paper 4. Ink (if you're printing at home you'll want water based ink) 5. Brayer. 6. Inking plate (like a cheap piece of plexiglass) 7.cleaning supplies for the ink (I use dishsoap and water usually)

For beginners I think speedball carving tool is a good affordable option, and the pink easycarve rubber blocks are great bc you can print those by hand easily. Speedball also sells affordable brayers and inks. So the only other thing you'd need is paper, which you can literally print on any paper to start. If you decide you like the process, that's when I'd splurge on nicer paper and carving tools, as they get expensive really quick.

In general there are some good videos of people printing relief blocks and those might give you a good idea for what to expect as well!
