... If you aren't using an ironing bottle, you should be -- it's a Coke bottle with a special stopper perforated with holes, used to sprinkle water on your cottons before ironing. Creates the same effect as a steam iron.
I remember one year during Vacation Bible School (of all places), we made ironing bottles as an activity. We used a Coke bottle and somehow had different colors of paint swirled inside the bottle. I guess it was a tie in with "Joseph's coat of many colors." I remember well that big sprinkler head that went on the bottle. My Mother used that bottle for many, many years. That was sometime pre-1960 when we did that project.
