For sending invitations you can have the following options.
1. Print out kitty party information on large address labels. Then stick onto pretty pink bandanas and send them out to your party guests. In the invitation ask them to wear the bandana in a creative way to the kitty party. The most creative use of the bandana wins a prize.
2. Embellish plain note cards with stickers of horses or cowgirls items such as bandanas, hats and boots.
3. Make cow spotted cards by drawing black spots on plain white note cards.
