You will need 4 equally long strips of paper or I sometimes use gift ribbon (just don't use the thinnest kind if it is your first time as it can be a bit tricky).
Fold the strips over themselves so they look as the first picture.
Then turn it around and do the same on the opposite side.
Then it will look like this:
Folk back one of the strips and bend the previous in under the one you lifted.
It will come out through one of the tips on the side, pull it out carefully so that a tip is created.
Repeat...
Eventually it will look like this:
Then do the same on the other side:
Then cut off all the snippets sticking out, and you have a little start
It was quite hard to take pictures whilst making the star but I hope you will figure it out. GOOD LUCK! :)
