So how was your day?
No, seriously - this picture shows how to take a scallop punch and make it into a border. First you must punch a 1 3/8" circle in your cardstock and then center the scallop punch over it so that you get what you see on the upper left. Snip it - as in the upper right, and then gently open it up. The paper will bend between the scallops - press it gently with your fingers. Then you can use it like I did below (part of an Easter project to be posted later).
