I finished a card yesterday with a Unicorn and a Rainbow under a cloudy rainbow sky.
The rainbow stamp set, from The Stamps of Life, rainbow2stamp, was released in July 2017 and has been in my stash that long. The unicorn is from Paper Smooches Spectrum set, released in 2015, now retired. I used several ink colors to make the clouds. This is a bright card that will probably be sent to someone needing a bit of encouragement.
