I need some MN expertise, please. DH bought me a lovely silk scarf from eBay, it's around 40" square but was sent folded down to an eighth of the size and vacuum packed. It's been lying flat on the bed all day but is still creased into loads of small squares. There's no care instructions on it (pre-owned) and I don't think my only nearby dry cleaners take unlabelled items.
How can I smooth it out without risking damaging it?
