We were shown this card idea during our online convention in November (2023). To create your window on the front of your card use a punch or die to create an opening. Using that same punch or die, create the shape in patterned paper (your own or pre-printed!) or some other paper. See my cards below for lots of ideas! This layout really ignited my creativity! Well done, Stampin' Up!!
I made a few cards in this video. You cans see the close-up photos of those finished cards below.
The strips for my inside and outside sentiments are scraps from trimming cardstock for layering. The Designer Series Paper (DSP) is from Let's Go Fishing found in the 2022-2023 annual catalog. The sentiments are from Heartfelt Hexagon, Quiet Meadow and Hope You Know stamp sets. The sprig can be found in the Timeless Arrangements stamp set.
