I recently broke down and bought a Cricut cutting machine. I'm still trying to familiarize myself with the machine. I borrowed the Hello Kitty cartridge from my mother and made these cards. With this cartridge you can actually make the cards shaped like the kitty as shown in the second photo. The other nice thing is that you can size them to fit into a standard envelope. The cards are easy to make, but rather time consuming, as you have to cut out glue multiple layers. I thought that Hello Kitty cards will sell well at the animal shelter, as she is loved by adults and children alike.
