I have my LA thread stored in 3 plastic tubs which I keep under my frame (and use as a footstool when I'm on the drafting stool). To make it easier to organize and be able to see all the cones, I made a "tray" of a shorter plastic tub, set into a deeper tub. That allows me to set the cones upright. I sort by colors (blues/purples/greens/blacks/browns in one; whites/grays/lights in one; yellow/orange/reds/pinks in 3rd). I put multiple cones of the same color into baggies and slip the bobbin inside the cone. This works well while keeping them dust free and not drying out.
