Initially wasn’t too keen on these curtains as they came out of the package very creased and the label says no ironing. However, after ironing another pair of curtains that appears the same / very similar fabric the label of which allowed ironing, I gave it a try and was able to iron them, using an almost entirely hot iron on the back. Now they look exactly as I expected them to look and I’m very happy with them. They also have good heat insulation properties, I kept them closed during the heatwave and the temperature between the curtains and the window was at least 60C.
