Remember the days of metal sprinkler caps with cork around the neck to fit tightly down into a bottle. I spent many a day spreading out all the cotton clothes, sprinkling them, rolling them up and placing in a plastic bag and then into the refrigerator overnight. Now I spritz fabric, roll it and let the water soak into the fibers and then iron.
Most important tho, is to let the fabric cool before moving it on the ironing board. Takes longer and this impatient gal
has to bide her time but it seems to help. If you move the fabric while it is still hot the wrinkles just rebound. Learned that from a you tube video of one of the younger men quilters. Can't remember his name.
