Snowflake card was the fastest. It was a 10 at a Time ATC front. Also, it was the last one I made. I had learned not to select stamps that required coloring by that time. This one is my second favorite. It came together nicely.
Sympathy card was the next fastest. It required coloring, but the coloring was in larger areas and quick to do.
The Comfort and Joy card is my favorite, but those berries--way too many of them! If you do something like this, stamp a stack of them and save the berry coloring for doodle time when you are on the phone.
