I found a great website for free shapes to cut with SCAL.
When you click on an image you want it comes in coloring book format. I prefer to "fill it in" in Microsoft Paint before I use it in SCAL.

Then you use the paint bucket and fill in the sections you want and then resave it (I would continue to fill in all of the sections):
Hope you find these helpful!
