Izzy we have a 5 draw unit for my DDs craft stuff. It's contains the following...
Pens, pencils, crayons, glue, glitter, glitter glue, scissors, paper, white and coloured, card, tissue paper, foam card, Pom poms, foam shapes, stickers, stamps, lollipop sticks, magazines, colouring books, glue spreaders, stencils, googly eyes, the fluffy wire things (forgotten what they're called), rulers.
We store paint and play doh in garage.
Hope that gives you some ideas, we took DD1 to hobby craft for her 5th birthday to fill the drawers
be worth a wander just for ideas.
