SO, I was trying to think of ways to make the letters unique (not buying a font or using a free font because they can look fake) and I came up with THIS solution...I took a piece of blank white computer paper and laid it over a yellow legal pad (lined) and wrote in permanent marker on the blank white copy.

I created my own font (from my own handwriting) and it looks pretty good.

I then found a font that looks similar to hand written words and typed my message and printed out 100 copies.

Sometimes the county requires a certain format as far as margins, font, etc. are concerned. 

One tip on your bandit signs - keep the message short & simple, no more than 3 or 4 lines of data, written in large block (capitals) font.  

Mine are so genuine I get people calling me to say, I am so sorry but we dont want to sell.Oh and find a good handwritten font on the computer to use.

Also, depending on your quantity, you may want to print with a handwritten font or maybe even outsource.Good luck!

Possibly make the font a different color or different color postcards so that you can track which mailing you are having the most penetration. 

The @Andrew Cushman has to show up in blue font for him to be notified of your question.  

Use different fonts, envelope sizes, colors, ect.
