I used to "beef up' my wire hangers with either plastic straws or with bamboo skewers taped securely to the hangers, but I removed them all after watching Ione from Eve's Garden Soaps make the most beautiful flowery hanger swirls with just a regular wire hanger still in its triangular shape. The soap pictured in my avatar is a soap I swirled with just such a plain wire hanger (wrapped tightly with Glad Press n Seal to line over the wire). Here's a bigger version of it to see the swirls up close:

The swirls I use to make with my 'beefed up' hangers always came out nice enough, but never as pretty as the swirls I make with my skinny wire hangers. I confess I'm really partial to my skinny hangers.
