I haven't done this yet, but am looking at putting up some command hooks and laying a curtain rod in them and then hanging all my scissors on s hooks and then on the second one my rulers. The holes in the rulers are too small to go over the s hooks so will tie a short piece of ribbon thru the rulers to hang them from. These will have mostly small rulers as I keep the larger ones in a ruler rack or guide (with grooves) on my table. They are the ones I use the most but will be able to hang them if I like. Just have to wash a spot with the vinegar as the command hooks say, let it dry and measure where I want to put the hooks. Then can lay the rulers on the hooks and start hanging stuff. Takes me a while to get some of my ideas implemented but I will get there. Been busy with the quilt club making those qults for the fire victiims and trying to get caught up and get some ahead so I can work on my own stuff.
