Does anyone know how to use patchwork cutters for fondant? I want to purchase a few, but I'm not very sure how to use them. I do have some idea. Anyone have some ideas for me? Much thanks!!

You can use them two different ways. You can use them to cut out the actual figure or you can use them to press into the fondant to make an impression.
For cutting them out, put a little crisco on your surface and roll out your fondant. Then press into the fondant like a cookie cutter. Then you can take the image and apply it to whatever you want.
For the impression, you want your fondant on your cake already and then press into the cake with the cutter but not so hard that it will go through.
Does this help?
