LOVE the colors from the today's CAS challenge and had to play along.
I used the watercolor spritz technique (it probably has a different name, but that's what I call it) :)
This is a 2-step stamp. I inked the solid stamp randomly with three shades of blue ink (used markers), spritzed with water and then stamped onto watercolor paper. Once dry, I did the same for the outline stamp, using only the darkest blue this time.
Fussy-cut the leaves and popped them up on a cork panel. Easy and fun. It's great that we can take creative license and make things whatever color we like ... am loving blue leaves :)
