Thank you for the pics of drawers and threads.
I'm not sure if these drawers are high enough to stand the threads upright. I had dry erase board cut to drawer size. Then hot glued golf-it's spaced accordingly. The T's keep the spools from sliding in the drawers.
Lovesquilting, What size drawers and what do you want to store in them? Here is another option. I use these for small items such as bobbins, sewing thread, etc. There are small organizing trays available that fit right in.
Check the co*ntainer store for the B*isley file drawers.
