I held a Kids Class earlier this month with a theme of Father's Day/Masculine Cards.
Here's what they created:
Tie Card: Special notes: The red tie was stamped on a separate piece of c/s and cut out and then "popped up" with stampin dimensionals.
Boat Card: The trickiest part of this card for the kids to remember was to stamp the anchors FIRST before running that piece of c/s through the cuttlebug. They liked sponging the water under the boat too.
Finally, here's the frog card. It was a huge hit - probably because of the googly eyes - what child doesn't love those ;) You may notice that the froggy is two-tone. The easiest way to do this (and still have usable ink pads) is to tap the stamp into your lighter color ink FIRST, then gently tap it onto your darker color ink next, THEN stamp it onto your cardstock. Both colors should come through in a mottled effect. For this card, the lighter color was certainly celery and the darker color was not quite navy. I used the same process on the sentiment as well. This technique works great for bolder image stamps.
