I am working my way through the Operation Write Home Design Boot camp (Boot camp page). The first lesson is 'The ABCs of Color (Basic Color Theory). I approached this lesson and chose to try out a card with the Monochromatic theme.
The pattern paper is from Colorbok, a Wal-Mart brand, and the solid paper is something I had in my scrap basket.
I can't remember where the brads are from they were in my stash. Finished card size is A2.
Go take a look at the design boot camp lessons, there is something for everyone.
Here a pic of the finished card, please ignore the blue clamps. :-)
