Modular Expandable Tea Organizer

My wife enjoys her tea and has a number of varieties. There are a lot of good designs out there but none of them were quite right. I wanted something that was easy to expand and could be assembled into a single unit.

Each layer slides onto the layer below with a simple dovetail.

My wife even asked for them to be color coded since having drawers in different colors makes it easy to know which tea is in each drawer.
