I have a box of wooden spools. Mine are the same as your they are old and break. Most of them were my grandmothers. So I got a clear lamp that you can put stuff in and dropped the spools in there. I put the lamp in the sewing room. It really adds something and I can look and imagine how my grandmother would sit and sew using those items.
I also have many needle cases. Many many years ago businesses would advertise on pin or needles paper cases. Some are big as a 4 X 5 with the logo cut out on the front. Very interesting. I have over a dozen of them. I am thinking I might frame them in the sewing room.
