I created my "chalkboard" in Publisher (you could use Pages, Photoshop or whatever program you use) First I downloaded a bunch of free chalkboard fonts. Just google free chalkboard fonts and choose your favorite site. I then searched for chalkboard backgrounds in Google images and downloaded that. Choose an image that is really smudgy to give it an authentic look.
I opened up a file in Publisher and started out by adding a picture of the chalkboard background I downloaded. I enlarged it so it covered the entire page. I then started adding text using a white color and in the various chalkboard fonts. I added the designs by creating them or getting them from the internet and setting their color to white. I printed it off and taped it in my frame.
Pretty cool. You can't believe how many people complimented me on my handwriting. Our secretary said she loved it but she could never write that beautifully. I laughed and told her to take a closer look.
I am just one of those people that is never satisfied with my final product. This was a much easier way to make a simple sign!
