Who needs the mail when you can deliver party invitations right to your neighbors' doors?
1. Use a computer to create the text for the invitation, and print it out on colored paper. Use clear glass plates or other circular items in graduated sizes to trace circles around the text in colorful layers.
2. Place a coordinating embellishment near the top, punch a hole in the center and thread a ribbon through to tie, and then hang on a doorknob.
