Ayla would love to have one of these for her crayons/ colored pencils/ markers. I'm thinking with colored cups that she can paint herself :) Use a wine rack and large cups to store markers, colored pencils. for paint markers and such.
DIY Colored Pencil Cabinet: Have you ever seen those massive sets of drawers big Faber-Castell sets come in? This is the DIY version, which can hold as many pencils (or pens, markers, or pastels) as you need!
Pencil Case for 120 Pencils - Don't bother with leather unless your pencils are worth a whole heck of a lot of dough! The canvas is fine - and, if you like, you could probably decorate/label it with fabric paints.
