Card 4 shows a cut out border at the bottom. The contrasting color shows through once the card is closed. The double sided cardstock is from my stash. Some are from Basic Grey, DCWV, Bazzill and other well known companies. The card bases are cut from Cricut cart Sophie. The layered embellishments are by Pebbles. The 3D butterflies and mini flowers are K & Co. The rub on sentiments is from the Mini Marks "Kate Sidekicks" set.
