How do I find wire hangers?

Depending on how many you want, Amazon or Uline. If you just need a few, try a local dry cleaners or uniform company. Check with friends and see if anyone works somewhere with uniforms that are cleaned by the service. They will be able to hook you up with plenty. Growing up we always had tons of hangers because of my dad's job.

What kind of wire hangers? For what purpose?

Go to a dry cleaner.

Oh man, I'll bet I've gotten rid of at least a million. Check ou estate sales, we usually just throw them in the dumpster

Have you tried thrift shops? I know I donate my old ones. :)

See if you can buy some directly from your dry cleaners.
