Magnets and vinyl washers with monofilament. That's the way I expect to hang my drawings in being in the woods. This afternoon over lunch I sketched the possibilities for hanging drawings in my upcoming show.
There are many issues to consider. Keeping the drawing taut, keeping the method for hanging as invisable as possible and maintaining an immovable space. Time to make some prototypes to test results. I happen to have all the components to build a test installation in my studio. Fabrication time.
