I’ve just washed my mortifyingly expensive lovely new merino wool baselayer and t-shirt for running. The instructions say to reshape while damp and dry flat, which I am used to doing with jumpers. But these are thin and they’ve done that twisting thing that t shirts do in the wash. I can’t reshape my way out of that, can I? I was just about to buy another set, but I’m having doubts now. Any insights?
