Tweety if you double click on a photo, or paper scrap you will get the photo properties box up, click on custom shape and select and you will find some shapes in there, click on the one you want and it will make a shape, click on invert and you will get different ones too.
You can make your own shapes but it's a little complicated so start with baby steps first. There are many standard shapes available to use such as hearts etc in the software. Enjoy and hope this helps you to get kick started.
