Straighten out your wire, Make a loop on the end for the hanger. Twist the wire around as tight as you can, then sand the end so it is not sharp...
I first put on a toy with a large hole to cover the wire, then started adding beads & stuff. I also ended with a large holed toy to cover the bottom loop. Don't forget to sand the end of the bottom loop also.
You can add toys in the loop if you want... I decided to stuff my loop
Then you take the finished beaded wire and wrap it around a round container.. I used a deodorant can, to give it the boing shape.
