Black Polyurethane Foam Inserts for Cases, 4 Pcs 16 x 12 x 0.5 Inch, Cuttable Packing Padding for Tool Box, Camera, Crafts and Storage

I bought these foam inserts and figured out where and how long to make my cuts to fit my bobbins, and then spent like over a week cutting out the slots after work 🤣 I messed up a few times, but it works really well, and I have a spot for every normal dmc color (would need another drawer or two for the others if i did variagated and silky etc). The dmc chest above holds black, whites, and ecru due to volume, plus threads that I had 3+ skiens of, variagated threads, and some random bobbins of colors I failed to note the dmc number for.
