I dreamed about a necklace like this a couple of nights ago and decided to give it a shot.
Find some bird images you like and trace the silhouette on to paper.
I googled some and then traced them straight from the screen - it works well like a lightbox.
Carefully cut out the birdie templates.
Place lots of little dots of blue tack on the back of the templates.
Stick the templates down on to black shrink plastic.
Carefully cut out the shrink plastic bird, cutting around the paper template.
Lay out the birds like you'd like them on your necklace and work out where you need to punch holes. Remember you will need holes to attach them to each other and to attach them to the ribbon.
I punched a small hole on the middle bird's beak so that I can add a charm.
Shrink down your birds in an oven until small, making sure to squish them flat after.
Attach a small length of wire through the wing of your first bird.
Thread on some red seed beads and attach to the second bird.
Attach the third bird in the same way and slip two jump rings on to the outer rings.
Add a small charm to the middle bird's beak if you want.
You can now attach this to a necklace chain but I decided to make two small cord loops and then attach it to a ribbon, as I'm allergic to nickel.
