Ikea has some of the greatest accessories for storage. I love this stainless steel hanger! It can be hung over the top edge of any door without the use of nails or screws. I have two of these right now and I need one more of my scarfs. I think this is brilliant and especially for small spaces with lack of storage. The hanger is from Ikea and is only 29 kr ($9.99)
I use one in my very small entrance to hang jackets and coats and scarfs I use the most.
I also have one in my little bathroom to hang towels and bathrobes etc. It gives me more space. As mentioned I also need one in my bedroom for scarfs.
