My favorite corner punch for my cards is the Southwest Punch by Marvy Uchida. I use it on lots of different projects. At Christmas time, I had to make a card in a big hurry, so I used the Southwest punch to make it look a little fancier than it would have otherwise.
I used the punch on all 4 edges of the card along with the layered blue & white papers. It’s an easy way to dress up about anything and especially when you only have minutes to complete a project! Happy punching 🙂
