I had seen these online and made my own variation of them. They are a magnetic cable weighted on the bottom and they come with 10 Neodyminium magnets that are powerful enough to keep photos, cards, etc. on the cable. See the photos below.
I hope you enjoy these. I will be selling these at the Tilley Craft Fair in November this year and any extras will be sold in my etsy shop... to be opened soon.
Until next time...
