Just as a thought, I know many of us have smaller spaces, but I had a fair amount of blank wall space, even after using a portion for a design wall. I used to use those round ruler hangers, from JoAnn's, but got tired of rooting thru all the rulers to get to the one I needed. So I just used some push pins and hung them on the wall, behind the door, dead space as it opens into the room and the door was right at the corner of the room. I found some room at the side of the closet to hang the smaller rulers together in the same way. I then decided to use the dead space by a bookshelf in front of the closet for the shaped templates.
I'll have to have my son show me again how to put pics on the computer and post. (Course now I'm obligated to pick up the room. I have to anyway, management company is coming next week to do yearly walk-thru, even tho' the lease is up in June.)
