I have this angled section of wall in my studio. It is a place where the roof line slants to accommodate the shape of the room.....this was an added space.
I couldn't install shelving here due to the angle. Then I thought of a VERY simple way to utilize the space. I attached dowels to the ceiling with silk ribbon that I had on hand.
I made three separate hanging rods that are staggered. They work great for my ribbons and clamps.
I have also used them for a variety of other tasks......for instance hanging projects to dry.
So, if you have a space like this, give it a try. Simple, inexpensive and very useful.
