When I moved into this rental house there were two extra ironing boards in the storage building. I have put them to good use! And I even sometimes use my own for actually putting one of those hot steamy things on my wrinkled clothing in a futile attempt to look more professional when I go to the paying job.
I had a prior post about uses for ironing boards (related to weaving). Here are a couple more.
Ironing boards have very adjustable heights--good for tall people. And the padding helps keep things like warping boards and dowels holding wet yarn from slipping. I imagine there are thousands of other uses for them that I have not yet experienced. Mostly one just needs the occasional portable work surface. (Of course the people who know me might just say that I should clean the other surfaces in my studio.)
