Here is a fun card I made for our grand-nephew who is currently really into robots. Lots of action on this one! I started with orange (a color I don't often use) cardstock and some robot designer paper. Next, I ran some aluminum foil with an embossing folder through my Cuttlebug to make the "electrical panel" - cool, eh?
The robot is actually from a Hero Arts Christmas Set ("Far Out Holiday") - he had Christmas tree antennae that I cut off and replaced with green pearls. I colored him with Copic pens and matted him with 2 layers (one of which I punched with a square and a circle punch) of cardstock.
I bet you've guessed what the mechanical part is that I added to the card with some stiff metallic ribbon. Finally, the sentiment is made with my trusty old Dymo label maker. Life's too short not to have fun!
