Yeah very easy.
You just cut around the top of each of the round egg sections so you have a little cup.
Then at every crease in the cup you cut down the side until you get to the round circle bit at the bottom.
Then you splay it out flat and cut out jagged shapes in each of the 'arms' and cut out the inside circle bit in (what was) the bottom.
Then you paint it with glue and cover it with glitter. Leave it to dry and do the other side then hang up.
Hopefully it will make more sense when you have the egg carton in front of you.
It would be cool for the kiddies to help with too - they could do the glitter application if you're feeling brave.
