I’ve found there many nicely looking stuff, like this hanger. I would love to have one like that instead of boring, grey, hangers we had at school. But to be honest I would prefer boring grey than the nuclear emergency that would give me a possibility to have colorful ones, even with those great shadows playing their part there ;)
