Everyone keeps asking, "How did you do that?" So I took a few photos, because a picture speaks louder than a thousand words. I did not come up with this idea. I simply read about it in the
SCS forums. I am posting picture in hopes that it will help all of you who had questions. I did my scallops on a thin strip of paper. This technique will not work for larger pieces of paper. I did find
a tutorial, by Natasha aka tashers on SCS, that shows how to do this technique using a corner rounder. I haven't personally tried it but it looks like it would work for larger pieces of paper.

All you need is a slip of paper and a slit punch.

Punch out your first slit. Be sure that your slit will not hit the edge of your paper.

On the next punch overlap onto the previous punch just a little. It is kinda hard to see here, but I tried.

When you have all the scallops you need, you can pull away excess paper.
I hope this has helped you get a visual on how to make your own scallop edges. If this has helped you please post a comment and let me know.
