Don't use the ink in your printer! It is cheaper to go to a local inexpensive copy place nearby. Use colored paper. When making personal flyers (and I love Jeffs-esp. with the mild revisions recommended) Don't use fancy type fonts that can be difficult to read. Use black ink. Basic and probably obvious suggestions, but I get a lot that are impossible to read because they are trying to be cute or original.
I think a bold Jehovah's Witnesses on it is going to detract. Make the safety of the kids important. Like one person said-most people just find JWs annoying and will likely dismiss your flyer if it looks like it might be one of theirs.
Good job Jeff-you are a smart guy and care about your neighbors. I like that!
