Creating fondant or gum paste decorations is easy if you use a mould. Sometimes finding the right mould is impossible, but you can make the mould out of food safe silicone. You can use several different types of silicone for making food moulds, but the easiest method uses two-part mouldable silicone product.

Things you need
- Original piece for moulding
- Silicone plastic or mould putty
- Parchment paper
- Masking tape
- Food-grade release agent
- White bread
- School glue
- Clay tools or toothpick
- Small round object
Tear the crusts off of four slices of bread and tear the white part of the bread into tiny pieces. Put all of the white bread onto a styrofoam plate.
Pour 1 tbsp of white school glue into the breadcrumbs and knead the bread and glue until it makes a smooth dough.
Make your original piece from the bread dough clay and let it dry overnight. Once it's dry, it's ready for moulding.
Open both containers of silicone and put the coloured piece on top of the white piece. Squish and squeeze the clay together until it is all the same colour.
Create a one-piece mould for flat pieces by pulling off a small pinch of silicone, and squish it into any deep crevices or delicate design areas on the original piece. Keep pulling off small sections of silicone, and continue covering the original piece until the silicone is about 6 mm (1/4 inch) thick over everything except the back. Leave the back clear of any silicone. Work quickly, so the silicone doesn't cure before you are done.
Form a two-piece mould for three-dimensional pieces by mixing half of each colour of silicone. Coat half of the original piece with a 2.5 cm (1 inch) thick layer of silicone, but not the bottom. Push a small round object into the 2.5 cm (1 inch) side of the mould when it starts getting firm. Pull the round object out immediately. You just want to make a key for lining up the second half.
Paint release agent into the key holes and across all of the 2.5 cm (1 inch) sides of the silicone. Let it dry for the time recommended by the manufacturers.
Mix the rest of the silicone and squish a small amount into each key hole. Coat the rest of the original object with 2.5 cm (1 inch) of silicone, but don't put any on the bottom.
Let the mould set up overnight, and carefully pull it apart at the seams you coated with release agent. Wash the moulds with warm, soapy water, and dry thoroughly.

Tips and warnings
- Some people use polymer clay or plastic to sculpt their original objects, but both products are not safe until fully cured. Bread dough clay is 100 per cent safe. If you are using a piece of lace or small, ready-made sculpture, clean it thoroughly before making the mould.
