Hi! I just did a quick search and found something that might work. It's billed as a closet bracket and is intended for holding a wooden rod for clothes hangers to hang on, but I think the shape might also hold a wreath. Plus, it's meant to be wall-mounted!

I also wanted to suggest another option. How about hanging the wreath on the inside of your door? That way, you'd get to see it more, and wouldn't have to worry about theft!

Congrats on your new wreath! After waiting and saving for so long, you deserve to enjoy it for many years to come :)
