The CMYK clothing butler is the brain-child of CMYK Sweden. According the company’s website, it’s not yet available for purchase, but for a DIYer with a jig saw, who cares? It’s totally DIYable! Three-quarter inch cabinet grade plywood (because it doesn’t have voids in the laminations) would be my first choice.
P.S. Wood workers who have a router and trammel could have some fun with this one. And speaking of routers, I’d probably run a round-over bit around the edges. For those without a router, a file could knock the hard edges down too.
