AI would find your designs online (even coloring pages), cut and paste to Word (or whatever software you have that allows you to change shape and size of the images, print on card stock and cut those out as templates. You can cover them in clear packing tape and cut again (I only do this for patterns I'll reuse or making multiples of) its like laminating them.
Roll out your fondant, I've never used fondant sheets but I imagine it is what it sounds like) and cut out with an exacto knife or scalpel (clean, cake only tools).
Unless you have a Silhouette cutting machine this is the easiest alternative. I use it all the time for projects.
Google Images will give you thousands to choose from - of most anything - just type it in and hit ENTER
Sometimes you need to rethink your search title.... a silhouette will give you the black outline you are looking for
