I have seriously started loving my catch-all tray. It's one of those blue (or I guess they could come in any color) trays with rounded sides and a spigot at the end with a plug. I really like how I can easily pour embossing powder all over my project, shake the excess into the tray, and funnel it back into my powder bottle!

And, the handiest trick of all in my book, is to shake baby powder (or cornstarch) onto the tray before I use it then brush the excess off. This ensures there will be no embossing powder residue left in the tray!
