I assembled card kits for my son's 2nd grade class. I used the Robot Party Cricut cartridge. I chose this one over the Robotz cartridge because it is only 2 layers & much simpler for the kids to put together. I have them all cut out they just have to assemble it. The gear on the front is a TH die. The kids will be embossing the white card front, die cutting the gear, stamping the sentiment on the inside & handmade by on the back. I already stamped &punched out the happy valentine's day for them as a time saver. I punched out the heart on the robot & added it. I think the one googlie eye adds a cute touch too. :) You can see in the picture that I flipped the robot orientation to align with the hearts going in the same direction.
