If they are a poly / cotton blend ( maybe for the kitchen or bedroom ) I
hang them and then use a spray bottle of water, set on a fine mist. They
usually dry with no crease. HTH Barbara in FL & SC
:
Every time I buy ready-made curtains they come out of the pack with
deep creases on them,

Hang them creased and puff steam at the creases out of the iron. For
really creased areas, hold them taut while puffing the steam at them.
and explore!
