First would be drawers of the right depth to take DVD sized boxes (The same depth works for stickles, ink refills, acrylic paints, punches and heaps of other stuff). Then the boxes to put in them that I would fill with stamps and dies. Maybe some shallower drawers for smaller supplies like embelishments and ribbon and definitely some deep drawers with hanging folders for 12x12 paper
Next an open shelf area, divided for my pencils, pens and markers, ink pads.
I have a good light but I have to admit, I'd like another for different areas.
And finally, a bench to stand at as I often like to work standing up - I get excited and need to move around for some reason.
