Have you seen this cool lightbox from Artograph? It not only gives you a way to take your beading projects with you but also offers lighting so you can see what you are doing through the transparent tray. You can even purchase additional bead trays for different types of projects. The following types of trays are available: Necklace, Design, Multi, Scoop, Jar, Project, Earring, Seed, and Seed Sorter. I haven’t bought one yet but I sure am very tempted
