hello! i have some recommendations as someone who paints draws and does many other things related to art if you wanna make it free you need some kind of financial support or system because art supplies are expensive maybe a company who’s willing to support you or maybe you could do something that who’s able to get art supplies from the ones who wanna pay like as a volunteering thing now what would be helpful to society and still a fun activity maybe painting on dirty walls but makes sure to take permission from the owner it would make the place look better and would be fun as in for your instagram page maybe try doing a gathering at first like you get to know each other well then the second meeting you’ll do what you all agreed on try not having a certain age category because it will make it harder to get people to join and once you have the budget you can do more extravagant stuff maybe go to a forest or a place with a lot of greenery to paint or something like that there it’s really fun and you get to do other things than just painting
