How or where you store food coloring and dusts? Right now I have them in plastic containers (one for dusts and brushes and one for colors) with lids so I can stack them. But I'm not super happy with this arrangement, looking for storage ideas.

AThat's actually a good question, I store my food colouring in the cupboard as everybody else uses them. My dusts I also store in a plastic box- I have been thinking about getting one of those plastic drawer thingies so everything can have its place HTH :D

I use clear plastic boxes with clear lids, just slightly higher than the containers (I too have one for pastes and one for dusts). Most of the colours I use have the label on the side of the container, so I write what colour it is with a sharpie on the lid, so much easier to find what I am looking for!

Hahaha, I use plastic containers for mine too! One for gels, one for dusts and one for liquid colours. In a perfect world, I'd have my own cake studio at home with dedicated drawers and shelves for everything. Not possible though! 

I dump them out of the original container into little bead containers, and store them in a bead drawer.

I just bought an insert at a local bead shop, looks like this, https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcSMROHS9znBdH4M50EghNGO-qFHCUkrYTUcO4axqkpXTXWq9527

The circle sin mine are smaller though, I think it has 100 slots.

by bead containers I mean little things like this, http://www.flickr.com/photos/oxymephorous/2295939297/

I bought a few packs of 20 or so at Michaels for a few dollars each.
