Three main ways, crafting, foraging and encounters for us, but working is also something we're going to do.
Bear is a high level of hobbyist craftsman/inventor irl so does his character. So he made potions of lesser healing from foraging for healroot and berries. He learned a recipe (there is a method to do that) that allowed him to make basically berry syrup with concentrated healroot for 2d4 healing. He had 21 of those and we sold 15 for 150gp and the recipe for 100gp plus 10% hereafter after negotiating a contract with the alchemist.
Next, in the forest we faught a hobgoblin with goblins and the hobgoblin miraculously had 5pp and some gem ore, obviously he had killed a drawf prospector and his ruined supplies and armor were in the lair.
Lastly we found a foot keg of reserve hobbit wine while foraging. That alone got us 50gp.
We do have a lot of furs but Bear could make more if he crafts them into boots since he went through all that trouble to learn the skills and invented the recepe/plans to make them.
We also had some misc treasures from foraging like dried apricots which were worth some crazy amount like 5gp each I forgot, but they were like 1/100 chance to find 1d6 and we got 5.
Foraging is a fun mechanic but without stealth you run the risk of an encounter 1d20 per hour. There's a small chance of an ambush or surprise encounter and if it's an owlbear good luck. Gwen took about 12 in-game days to learn stealth, Bear and I both had it from surviving in the wilds for more than a year each.
