My teenagers and I started out a few years ago making items for fun, for family members and for my students (Middle school teacher here). After lots of time creating and lots of research, we began going to conventions that were nearby selling handmade items. This led us to developing an online store that is run by myself and children.
My daughter has been working with digital drawing/painting programs turning her fan artwork into homemade pins and stickers. My son loves to do pixel art and gathers ideas to sketch into pixel form using graph paper and colored pencils. We are still pretty new but look forward to growing our shop every week.
