Notes

Care labels show an iron symbol with one, two or three dots: one dot is about 110 °C (230 °F), two about 150 °C (300 °F) and three about 200 °C (390 °F). A crossed-out iron means do not iron. Start with the lowest setting and work up, iron synthetics inside out or with a pressing cloth, and test a hidden seam first.
