The challenge at AAA Cards is to use a 1" strip with an optional of a colored card base.
My strip is just less than 1" so I could cut a true 1" in red to back it. I stamped the Simon Says background stamp ( 2019 Leaves and Berries) with Whisper ink on Fog card stock, colored with Copics, and did the berries with Nuvo drops. The sentiment is from a mini Pretty Pink Posh set. I also stamped the fold on the envelope with green ink.
