If you sign up for only one pay site, the Kidology site gets my vote. It is well worth the investment to be able to network with others, gather skits, scripts, lessons, object lessons and so much more all at one site.
The Good News in Color for Kids by Rev. Dennis Barta. Most witnessing tools for children are designed for adults to share with kids; this tool is designed for kids to use with kids.
Using silly bands in special shapes and colors, children are able to tell a friend how to become a Christian. A gold house represents HEAVEN, a black cloud represents SIN, a red cross represents JESUS” DEATH, a white snowman represents FORGIVENESS FROM SIN and a green tree represents GROWTH. The accompanying color tract includes an explanation and Bible verse for each step.
The Gospel in Colors is sold in packs of 10 for $10. Limited supply.
