For your rulers, You can use one of those really big, (they are similar to a small key ring), but are about 12 inches across. Because all of your rulers have a hole in the end, it is easy to retreve whichever one you want. I also use a wooden ruler holder. They hold your rulers and are very easy to store. I have one that attaches to the wall and one to set on the counter. The one on the wall is more slanted. Good luck and hope you enjoy your new room.
