I used the two images from the Pets Quartet stamp to make the "window" shape, added a strip of chenille rickrack, two fussy-cut cats from the paper scraps in my cat and dog box, and then added a button between them.
And this card doesn't follow the inspiration sketch at all! I really wanted to use the black cat--the last scrap from those papers--because he reminds me so much of my cat Mr. Jones. I added a tag with the images from the Pets Quartet stamp and some blocks to spell CAT from Tim Holtz paper. The finishing touch--some pawprint stickers.
