I could fill a small sewing shop with my supplies!
I have a hand sewing box though, for my hexies and any other hand sewing. It's one of those 3-tier clear plastic bins that snap together and the top has a handle. The top compartment is divided into little cubbies for my pincushion, needles, thread heaven, thread, snips, hexie templates, etc. Middle and bottom are probably about 8"x5" and about 1-1/2" deep each. Middle one is scrap squares, bottom one holds all my finished hexies and assembled "flowers". If I take it somewhere to go, I leave the bottom bin behind. If I need to do general hand sewing I only take the top section. It's very handy.
