Firstly find some stray branches the size you want for your tree.

Now on to the leaves.
I found the pattern for the leaves here:

I would write them out, but the photos really helped me with the last bit.

Make as many leaves in as many colours as you want and hook them on to your branches.

Pop them in the vase and decorate your tree with either hand-made decorations or shop bought (we had LOADS left from last year, so i used them). I had bought some foam flower shapes (for my daughter to use) so i added some of these also.

I then threaded some easter sequins on to some cotton and hung these from the branches.

Now, display!
