Hi Terril, welcome to Orchid!
When I string beads I usually use fishing wire. Started doing
this when I was a teenager and my dad had fishing equipment down
the cellar. I still have some of those things now and they are
still in one piece after much wear and over 10 years. The end
knots I melt lightly with a flame so they won’t undo.
Are you originally from the New Haven area? I grew up in
Bridgeport and my husband is from East Haven.
