The existing curtain icons show two curtain panels closing from both sides. I personally have a lot of curtains that only close from one side, which I wanted to be able to display in home assistant. I tried my best with a svg path editor to edit the existing icons and would like to share the results here.

I hope it's alright I bundled the icons into one ticket.
