What you will need is;
Wired twine in color of your choice, ( chose Purple for a little girl.)
Hot glue gun
Optional to add stickers, flowers etc...
Bend the wired twine to make the name and wrap the ends around the "pants" part of the hanger and hot glue the ends to the wood.
Tie a pretty ribbon on the metal part of the hanger.
Add bling! Maybe flowers, stickers, beads etc..
(not for a baby obviously, for safety reasons, but to hang on a wall as decoration:))
P.S You can also use galvanized wire to make a sturdier version but its much harder to shape.
