Here are 3 of my cards.
The first one is a stair step card. Instructions and measurements can be found at www.splitcoaststampers.com
The 2nd card is 5.75"x 5.75"
The last card uses the beautiful Heartfelt Creations die from the cascading Fuchsia series.
There was a fourth card but I forgot to take a photo of it. We shaped a poinsettia flower out of vellum.
