I hit both challenges today with my guy b'day card - the CAS challenge was a sketch and the Technique challenge (hosted by Vicki Dutcher today! whoo hoo GF!!!) was to use piercing on your card.
I pierced my top corners and along the bottom - connecting the piercings with a drawn black line. I sponged the clouds using my cloud template, the punch is EK Success.
Accessories: sponge, word window punch - SU, EK success punch, cloud template, big brad - American Crafts, paper piercer, mat & Grid - SU, black micron pen
