Rules and etiquette:
Anything related to worldbuilding be it maps, lore posts, drawing, discussions, questions is all welcome here. Go nuts!
If you're new to the tribe you can do a post introducing yourself or your world. Welcome!
I've seen useable maps done in something as simple as Paint, but I urge you to download GIMP (which is free) and try to get into that. Check out a few GIMP worldbuilding tutorials to learn a few tricks and play around for a few hours. You'll soon have something much better than a coffee-stained piece of paper ;) (not that it is a terrible technique I think it's a creative way of creating randomized landmasses but it needs to be further processed IMO)
Edit: Or if you just want to get to the next step quickly just take number 2 (which I have a feeling is the one you prefer) and start worldbuilding with it :) You can always redo the map at a later point in time.
How obvious did I make it that 2 was my favorite haha. I'll most definitely install GIMP! :)
