How can I hang - or otherwise store - cardigans while keeping them in wearable condition?

I have a heck of a time hanging my cardigans without them getting little hanger-dents in the shoulders. I’ve tried folding them and putting them in drawers, but then they just get wrinkled.

Has anyone found a way to hang or store cardigans and avoid dents or wrinkles?

It’s getting to the point where I wish I had a plaster cast of my upper torso that could wear them for me.
