To be perfectly honest I'm not sure where the 'fairy bread' name for this one comes from - but it's colourful and easy to make, so it's bound to appeal to young children.
You will need:
Butter (or margarine or what ever spread you want)
Hundreds and thousands
Butter the bread, then sprinkle hundreds and thousands on the bread. Cut out shapes with the cookie cutters.For a variation you could try different spreads - Nuttella for a dark (and tasty) background colour or perhaps honey for a stickier surface (and stickier fingers).
Consume at your leisure! :-)
