Last friday I went to game night with my mom and her friends. And of course there was wine, and of course it was St. Patties themed, so naturally I had to make wine charms. These were super simple and it cost me WAY less than $1 for all of them.
I had a bag of little "foamies" shamrocks in 2 different color greens. All I did was sandwich hemp chord (you can use ribbon or string, whatever works) between two sharmrocks with hot glue. Then I wrote our names on them.
Done. Yay. Easy.
You could easily switch this to any holiday or theme. You could also put a rubber band in between them so you could wrap them around a can or bottle or cup.
