Before you start, you will need to find something appropriate to melt your beads in. I recommend metal cupcake baking trays, but for this I used oven-safe, rubber mini muffin moulds.
Line your moulds with tinfoil so that you don't wreck them, this also gives the plastic a nice cracked-candy look.
Fill each mould with coloured beads, so that the bottom surface is completely covered. I used a mixture of clear beads and solid beads to make different kinds of 'candy'.
Melt down in the oven, set at it's highest heat. This should take about 30 minutes, but keep checking to make sure they don't burn.
When the plastic has completely cooled, remove the tinfoil. You should be left with little, round, plastic plates.
Cut a long rectangle of cellophane and two lengths of jewellery wire.
Place a plastic candy in the center of the cellophane and wrap up.
Twist either end of the cellophane, as you would do with real candy, and wrap the wire around to secure in place.
Repeat this with the other side and cut off any unwanted cellophane from either side.
Make a whole bunch of these.
Attach a length of string to your candy and hang on your Christmas tree.
