FRAME RACK (concept render)
Square steel tube and wood modular clothes rack. A few variations as well as alternate flat steel/round wooden rod version. I'm particularly fond of this design.
My current thinking on the materials is that the wood probably isn't necessary; an all-metal version would look very nice, too.
Bonus: "Bird on a Wire" coat hanger I made years and years ago.
BELOW: Alternate "flat" version.
