Linen in the freezer questions...
Learned this one from my grandmother. Can work with any fabric, but works especially well with linen.
After washing, roll it up and put in a plastic bag and place in the freezer. You can go back and iron it in two hours or leave it there for days if you're like me.
Why? Well, those stubborn wrinkles will disappear like magic when you iron it.
Why this works?
First, the fibers are now totally saturated with water. Second, the freezer part means no mildew. And third, and here's the part that I don't have time to find corroboration for at the moment on the net - when the hot iron is applied, the water goes from its solid state to its gaseous state and that's part of the magic.
All I know is it works for me. LOL
