It helps to have a paper stack that has lots of graduated colors in it when you want to do a monochromatic card. I used a 6 x 6 pad of Core-dinations ColorCore cardstock for this Congratuations card for Celebrate the Occasion.
I picked these three blues and embossed each section to give them some "life". The top section is embossed with the Tim Holtz Cracked folder and the next two with the Tim Holtz Bricked. I lightly sanded to give it some dimension. CAS all the way.
