WASH BY HAND! ? number I adopt the slut approach, bung it in the machine (40 degree, 30 if you are not sure) with anything else that is unlikely to affect the colour, take it out, stick it on a hanger, leave to dry.
I will admit to only using wooden hangers, but they were on a special offer so there!
I have about half a dozen "crinkle" skirts and one blouse. I wash by hand, squeeze as much water out as I can, then tie them in a knot and hang them on the line. When they get to just damp stage, I undo them, give `em a shake, then hang them back out again till dry. No problems, and, best of all, no ironing!
I bought a crinkle look dress from Marks on line and when it arrived I was horrified by how crushed and crumpled it looked. But I have to admit it doesn't look so bad on.
..And dry like that. How long do you keep it up for? This is a blouse from M and S. It's just looking scruffy now. I'm going to have to iron it and lose that casual look.
