I am a new devotee and can not afford any kind of stuff for an altar or offerings at present time, I plan on trying to assemble something once I can, but what can I do until then?

Don’t worry about it anon, you’re not obligated to buy anything to be able practice your faith 🙂
It’s not necessary but if you want to make an altar, I really like making them out of stacked stones.
As for offerings there are things you can find and give, or do for free like: things from plants (like seeds, flowers, and leaves), feathers, a sip of your drink (poured out with a statement/intent of offering), devotional art (music, writing, drawing, etc.), and meditative prayer, I’ve also listed some other offering-actions that you can do for Thor and Tyr, and Freyja. I’m working on making lists like those for all the gods in time, I think Fenrir will be next…

Seel!
