I started this design by looking at my edger and border dies. I decided a very simple card with a frosting edge and cardstock colors to mimic a cake.
Such a great use of that border die.
I am amused that you intended this to look like a cake, because the first thing I thought of when I saw the color scheme was neapolitan ice cream! 🙂 The border die you chose is an eyecatching take on the scallops!
