I wonder.....?

Last week I was sitting under a couple of birch trees in the centre of Dublin having a coffee.  Things kept dropping onto me and I started to brush them off when I realised that they looked just like tiny ivy leaves.  They come from the seed heads of the birch trees.  I gathered a couple of the seed heads into a napkin and took them home.

I am going to let them dry and see if they remain stable.  If so, I will use them to make a little trailing ivy plant.  I would be interested to know if anyone else has used these successfully as miniature leaves.
