My older daughter and I both like to sketch. We sometimes go the the Art Directors Guild’s figure drawing sessions here in Los Angeles on Tuesday nights (only $(removed)!) or we sit on the floor of her room and sketch whatever we want. (I like to use old black-and-white photos I find online for reference.)
To store my pencils, charcoals, lead holder, erasers, snap-blade knife, and reading glasses I bought a Lihit Lab Teffa “book style” pencil case ($(removed) on Amazon). It’s not large, but it’s designed with “pages” to hold your stuff efficiently. Pens and pencils fit behind straps, and smaller stuff can be stashed in the mesh pouches.
Below, a couple of my recent sketches.
