My girl is approx. 36" tall. I made her using the cowgirl applique shape in the Churn Dash Round Up quilt pattern. It's a fun pillow made with scraps.
If you make one, be sure to buy a Big bag of stuffing.
You could use any of the appliques from the quilt pattern to make large or small pillows.

Enlarged applique is fun on the back of a quilt too.
