I got this idea from a beautiful bird decoration I have. I realised that it was just a mirror shape of a bird folded up with some parts glued together and some folded open.
I made a Mirror Bird Template that you can print out, or you could also just fold a piece of paper in half and draw your own bird shape on it.
We did some really messy finger painting to show any decoration technique will work.
Cut out the mirror shape. Instead of decorating the printed shape, you could trace the shape onto a piece of paper already decorated in a previous creative session.
Fold it in half, glue two end of ribbon inside the body and glue just the body part together. Leave the tail, wings and head feathers not glued.
Clip and curl the feathers a bit.
Hang the birdy up and then tweet about how beautiful it is.
