Cookie cutter from photo

Does anyone know tips or tricks for creating cookie cutters out of phots. I’ve tried 3 so far, 2 come out perfect and the 3rd will not place a backing on the cutter no matter what I do. The images are all turned into coloring pages so I am not sure what is keeping the 3rd image from generating correctly. It will generate but will have a lot of separate pieces that are not connected to anything due to no backing. I can’t find any videos on creating cutters from images on cookie cad. Appreciate any suggestions or direction anyone can provide.
