I need to have the words backwords, like when you hold a piece of paper up to the mirror and you can read it that way.
You can do that in Draw
- Create a text box, type whatever you want.
- Modify > Convert > To Curve (or Polygon or Contour, there doesn’t seem to be any difference)
- Modify > Flip > Horizontally
Note: since in step 2 you convert the text to a shape, you no longer can edit it (they become separate objects). If you want to modify the text at a later stage you should delete the object and start again from step 1
Maybe there is a more efficient way to do this…
Ah! It was the convert phase I couldn’t work out. I had the “frame” selected, and that greys-out the Convert options. (Unfortunately “Flip” doesn’t (yet) apply to frames.) I suppose the advantage of Inkscape here is that you can “type” and modify text-as-text in mirror, upside-down, whatever orientation.
I can’t see how to do this in Writer or Draw, but it’s very simple in Inkscape! 
is that any help?
Even better. Export document as a PDF open in Inkscape and flip it.
It worked great for me.
