This post is in answer to Maria, who asked for a Hello Kitty sandwich idea. If you don’t have a Hello Kitty cutter handy, you can make your own reusable stencil with a picture printed out from the net, a plastic sheet, and a few household items.
For the plastic sheet, I used an inexpensive, thin and flexible plastic cutting board that I picked up from the grocery store. To make the stencil, secure the picture to the plastic using a clip to prevent the picture from moving, then cut with a scissors.
Place stencil on the bread and use a sharp and pointed knife to cut around it. Use a slice of whole wheat and a slice white bread for contrast and finish with cheese eyes, nose, whiskers, and flower. Hope you like it Maria! 
For a simpler Hello Kitty sandwich, use the stencil to cut out HK from a flour tortilla like I did in this DIY Ferb post.
