You might paint, needlepunch, rug hook or do applique, and like the rug, but don't really want it traced on linen. I'm now offering a paper copy of the basic pattern in my etsy shop Cotton Eyed Jo. If you'd like to make it larger or smaller that will be permitted in the paperwork of the pattern. This pattern is approx 11 inches by 15 inches.
I fiddled around getting the paper pattern done, because I thought if another rug (completely different) say more primitive style, with a Siamese cat with much simpler markings it might seem more achievable. I worked from photos of our Kirby Kat, and captured his likeness well enough to make it a keepsake. He won't be with us forever, but the rug will last longer than we do.
Don't forget to turn out the lights for Earth Hour tonight!
