So I'm in uni and I wanna make some money without getting a full on job. I'm not amazing at art but I do digital drawings and usually draw little random goobers! And I thought I could make them stickers but I don't know how, where, etc, I'd be selling. I was also thinking could I sell digital stickers or small digital assets? Just something fun people could spend a dollar on for no reason! Could I do a patron thing, like a dollar a month for fun little goober art? I heard people ship out these like sticker filled envelopes through subscribing to mailing lists, could that work/ be a good idea? I guess I'm mainly trying to look for something that doesn't take up a ton of time and something I can make look good while still developing key art skills all while making some cash to support myself!
