I haven't tried window cards too much but my neighbor gave me some so I have been playing around with different ideas.This one is very CAS
The flower stamp set is Painted Petals from SU. The inks are Certainly Celery and Wisteria Wonder both from SU. I stamped off once to make softer colors. I stamped the inside stems first. Since the stamps are photopolymer it was easy to overlap the stems and do the ones on the front. Then I stamped the flowers. The front sentiment is SU and the inside is one I found at a yard sale without a label. The ribbon is from my scrap stash, I think it is also from SU.
I turned the sketch from Case This Sketch upside down.
