More than a scallop edge....

In addition to the card I showed HERE using a scallop edge, you could also place the fancy scallop on your envelopes. If you cut off too much of the sticky stuff, use a little adhesive to close your envelope (I don't like licking envelopes anyways!)

Here's another idea for your SCALLOP EDGE PUNCH. Remember, it's on sale, 30% off the regular price thru Sunday night.
This is a medallion.
The bigger medallion starts with a 2-3/4" square. The smaller medallion is a 2-5/8" square.

Center the punch on one side of the square. Punch.

Rotate 90 degrees, center the punch on the side and punch again. Rotate, center, punch. Rotate, center punch. It's easy as 1-2-3.

I'd place a small stamped image, layered, on the inside of the medallion. Look for the medallion on a card in the future...wink, wink.
