i’ve been looking into starting making beaded wall tapestries based off of crochet filet designs. i’ve been looking at inspo pics & i keep seeing a hanging option that looks like a bar that the top bead can slide into. i am trying to figure out the name of these so i can source them to use. also, if anyone has used these, what size beads usually work best? do round beads work? i added some photos to show what i’m talking about. thank you guys in advance! ⋆˚꩜｡

edit:
to clarify, i want to buy the tracks to use. i am unsure what search terms to use to find them/dont know what they called.
