As far as the paper goes, there are a number of options. You could pay to have them done at most picture places, but that can be costly. You can use magnetic photo frames (pouches):
which I found
on-line but have seen at K-Mart recently (last few months).
Last is the true magnetic paper which can get costly also.
As far as making the images, I think there are a bunch of programs being used, Photoshop, Publisher, etc. You could do them in any program you feel comfortable. If you knew what you wanted, you might even find someone on the thread who could put it together for you??
The font needs to be in the "fonts" directory on your computer to work. Depending on the type of font, it may need to be installed vs. just copied. You may also need to restart (or dog out

) to get it to work.
