Here are some fun ideas.
Here's some ideas Joe, that twig scarf holder is pretty!
Coat hooks mounted to a piece of hardwood veneered plywood, then hung on the wall.
A vintage ladder propped up against the wall, would look lovely hanging from the ladder rails
You're a sweet guy, she's a lucky woman! I bet if you took a piece of wood, drilled some larger holes in it, stained the wood and pulled the scarves though, that could be a cool look.
An old fashioned wood accordion style cup/ mug holder would work ... But I do like the idea someone else posted about a ladder !
