Tape up all the cracks on a cardboard box, and use that as an enclosure for the mold. If you intend to make a one-sided mold, simply mix the silicone, pour it into the box, and coat the item to be molded with mold release and press it into the silicone, and let it cure. To make a two-sided mold, you'll need to create a tube for the casting material to enter, and another tube to vent the displaced air. You can easily create these by securing two pencils to the item with some putty. Coat the whole thing with mold release, even the first silicone mold (silicone will adhere permanently to other silicon otherwise) and pour on another layer of silicone, completely covering everything except the ends of the pencils. Allow that to cure.
