Edit: For the ironing performance I have now but deduct 1 star. It's not the material that can be ironed super. The problem is the sleeve. They're incredibly pestig to iron. After washing, the edges again hinzubekommen clean is almost an impossibility, no one wants to creases at the seams like. So tormented I have long gone largely because the sleeve can be clamped somehow on my board anywhere on such a small thing, to tighten them when ironing. Maybe that's better at larger sizes.
