Gather supplies. (I show you how to make the stamps using a Cricut Explore Air in the video below).
Add select images to Cricut Design Space. I chose various images (a unicorn, star, heart, dinosaurs, etc) and size the images according to your wooden blocks. Mine were sizes around 2 inches each. Set your machine to cut Foam.
Use a heavy grip mat and place foam sheets to cut on your cricut machine.
Cut the images. I used my Cricut Explore Machine with the Deep Cut Blade to cut 6 images in less than 5 minutes!
Use Tacky glue to attach to wooden blocks and let dry overnight.
Use the negative portion of the foam sheets (it looks like a stencil) to draw the image on the opposite side of the blocks (to label each stamp with the image).
You can also cut vinyl instead of drawing but I simply drew the image on the blocks.
