If you are anything like us you will have loads of broken, half chewed and blunt crayons, so this is a great way to reuse them and also make multicoloured and non-rollable (ours always roll off the table and snap) crayons.
All you need to do is snap up the broken ones - minus the paper of course. Pop them in a heatproof mould. Mine were 99p silicon ones from home bargains and we use them for ice cubes and then heat in a low oven for about 1o mins.
Then allow to cool, turn out and you have funky crayons, that are great for little hands, compact enough to go in travel bags and don't roll off the table.
I am not organised enough to match our fruit mould to colours, but you could. My boys love them and they make great presents for friends with little ones starting to use crayons as they are easier to hold than regular ones.
