How-To: String Art Card Display

I never quite know what to do with all the holiday cards I get; they fill up the fridge pretty fast, and fall down in a pile if I put them propped up on the table. I love this Christmas tree string art card display–it’s a fun decoration as well as being super useful! I can easily imagine customizing it for other holidays: a menorah for Chanukah? a heart for Valentine’s Day? (Via Sister Diane.)
