I did complete a card on World Card Making Day. The stamp set used is Martha’s Flowers from Joy Clair.
I have used this maybe one time and had quite a few pieces ready to watercolor. I chose one and began coloring. I used Stampin Up watercolor pencils. This will be linked to the Joy Clair challenge #2: https://joyclair.typepad.com/blog/2019/10/world-card-making-day-2019-with-joy-clair-challenge-2.html
This was the only card I created on World Card Making Day. It was enough for me.
