Merino wool sweaters are a softer alternative to traditional, scratchy fisherman's wool, with less stiffness and better drape. However, they can become wrinkled if you don't fold them neatly before storing. Ironing a wool sweater can burn the fibers and leave a sheen, but if you need to wear your sweater right away, washing it and drying it flat isn't an option. Use an alternative method to iron the wrinkles out of a merino sweater without the iron touching the fabric.
Lay the sweater flat on an ironing board. Smooth out the wrinkles by hand as much as possible.
Plug in the iron, set it to the wool or medium-hot setting and allow it to heat up. Place the iron so it is not touching the sweater as it heats.
Wet a clean, lint free hand towel with water and wring out any excess. Lay the damp towel over the wrinkled part of the sweater.
Press the iron against the towel and hold it in place for two to three seconds. Lift the iron up and set it down again. Press the entire towel in this manner. Do not rub back and forth as you normally would, as this can flatten the wool fibers.
Remove the towel from the sweater after pressing. Allow the sweater to dry before putting it on.
