Please forgive the absolutely horrendous mouse cad work here...
Looking to see if anybody might recognize what these things are.
These little doodads are about the size of a half-dollar. They are [the black] a ring made of a heavy/stiff rubber, or soft plastic. The areas indicated in gray [same material… colored for clarity of description] are thinner, semi rigid flanges that could flex.
You could pull or poke a tuft of material through the center and it would be gripped, and held by the flanges, but the tuft could just be pushed back through the ring from the other direction to release it.
Seemed like it would be handy for joining two TQs together, one on top of each other, for colder weather.
Back in those antediluvian times when I was a little kid, I think my mom used to use them to hold our sheets and blankets together so that they wouldn't get tangled, or kicked off the bed
Anybody remember them... And/or know where you can get a hold of some?
