One of the girls who comes to Card Club brought this idea several months back. It uses the SU scallop border punch to create an embellishment for cardmaking. I expect you could use any border punch!! I cut a 2.75" square of cardstock and centered and punched each side to create a decorative slot!! Each was decorated differently - I stamped a coffee cup with bleach on the brown one, embossed flowers in silver on the pink one, silver embossed candles on the blue one and added layered punchies with a bard to the yellow one. It creates a frame that can be filled with just about anything.
I added a rectangle of embossed cardstock into the slots and a rectangle of scrapbook paper to the front of the card before all the other elements were added. Again, a greeting can be added on the lower right when the time comes to send out the card.
I always enjoy finding news ways of using the tools I already have!! Not sure where the technique originated but thanks to all those who create and share which inspires the rest of us to get at making art!!!
