Making new crayons out of old ones is fun, easy and really costs nothing if you’ve got lots of broken bits of crayon around the house.

1. Take all of your old crayons, peel off any paper and break them into small pieces.
2. Let the kids place them in muffin tins, in any colour combination they like—pink and purple for girly girls, shades of blue for the sea, a little bit of everything, a rainbow.
3. Pop them in the oven at low heat and keep an eye on them. They should take about 15-20 minutes to melt but you want to take them out as soon as they are soupy.
4. Stick the tray in the freezer for about an hour and they should come right out.
5. Do some art!

If you want a posh instruction guide for doing this, try Martha Stewart’s version! I also like the instructions on the cute website Make and Takes, which is where I got the picture I used in this post.
