I found a quatrefoil in the new Every Avenue music video! At 3:18 there is a quatrefoil window, I was watching it while on the phone with my friend and they thought something was wrong since I got so excited!

Pottery Barn also has a quatrefoil frame right now! I saw it while I was shopping with my mom the other day and bought a few!
