That's my hand, to show you the sizes and shapes.
You only need a minimum to start : a sharp knife to cut the paste, something to make a hole, and websites suggest small cake cutters to cut shapes. We just bought some, haven't tried yet.
I hope this makes you want to try it. It is great fun, you can do it with children, and you can use them afterwards on bags, as decorations, etc...
Here are 3 batches on an A4 piece of paper.
