I'm a little late on all of the above. The Midweek Throwdown was for an Easter card. I got this stamp from the Outlines booth at the last rubber stamp show in April, 2012. I've heard they closed up shop. :-(
I've been continuing my Boot Camp work and came up with this for analogous. I guess it could also count for colors based on nature. I got the stamp at a yard sale. I have a lot of large stamps that just fill up the whole front of the card and I've become so used to having a lot of "stuff"- mixed patterns of card stock and ribbons and brads etc., that just having one big scene on the card front seems plain. How sad is that?
For my last trick, I used purple and green as my complimentary colors, and a SU stamp set, from Kim.
