i'm a polymer clay and mixed media artist. growing up i always loved teeny tiny replicas of big things like food, buildings, people, etc... I'd have them all organized and in their designated categories.
so ya don't mind the info dump, i'll share my very beloved art supply and craft collection
paints, Inks, mediums, glues
designer paper, art papers of all types, stickers, washi tape
pencils (watercolor, drawing) markers, gel pens
stamps, molds, stencils,embellishments
pigment powder, glitters, embossing powder, mica flake, gold leaf, foils
polymer clay, clay tools, findings, wire
plus stuff to put all this crap on top of (canvases)
i've make like a hundred wall art pieces but like 500 clay pieces (small usually)
they make great fidgets
