Just to mention, I downloaded the (free) Waltograph font and use it in Word and Power Point (and Elements) I make my own magnets with Power Point (which allows me to overlay fonts on pictures easily). If you find a graphic you like and you have permission to use it, you can add your own personalization in this way.
Furthermore, if you want to make your own graphics, using free photos and the mickey head shape makes it easy. It's a little more work, but still doable.
