Updated with a better photo: I used a Scrapbook Adhesives Keepsake Envelope to hold a tuft of my dear Uno's hair. He was put to sleep a few months ago. I took this photo when I was home last fall, which is the last time I got to hold him.
Details: Kitty papers are by Bo Bunny Petshop line. "Uno" was cut using the Lyrical Letters Cricut cartridge.
