My DS has a wonderful teacher who just hadababyitsaboy. He and his band mates needed a card for approximately 70 kids to sign. Thank God in heaven or 12 by 12 paper! Anywho-I used New Arrival-because it has it all, and I see no need to get yet another baby cart since my babies are on hyper-drive and growing like weeds. I loved making it! It measures 6 by 12 inches, and I matted the entire inside to allow room to sign away. The little train is cut in the top layer, blackout (to add stability I used Kraft cardstock) and shadow in white. Enjoy!
