My grandmother did this with all her fabric and cotton dresses that needed to be ironed. Her reasoning was that after washing and drying partway, the freezer kept mildew away til she was able to iron her goods. She lived in Florida where it was a problem. I asked her why she didn't just spray water or starch on them before they were ironed, and she said that all the items ironed much better coming from the freezer. Peace, Brenda
