Use Vinegar When Lengthening Garments

Sometimes when you lengthen a garment the crease line from the previous hem remains. The way to get rid of that is to moisten the crease with vinegar, and iron on the hottest setting allowable for the fabric. I always use a press cloth to protect the fabric.

I've been doing this for years very successfully. This is a great solution when styles change or you want to let your growing child wear clothing a while longer.
