Come One, Come All to a Circus Birthday Party. For a couple of months we have been developing a Circus party for 2 special children. Here are the invitations that were created with the help of Microsoft Word. The invitations will be mailed in a box mailer from Paper-source.com. It will include a clown nose and a clown lollipop as pictured. The event is scheduled for May. I can't wait to post the pictures.
