3. Add shadows
To create a shadow for the flip note you can use the wall shadow, but you will not have the correct shadow for the flipped corner.
Create a black rectangle and add some transparency and feathering. I used 3.9 pixels for the feathering and a transparency of 61%, but the feathering
and transparency depend on the note size.
Put the shadow rectangle to the background using Arrange > Move Backwards or the shortcut Shift+Ctrl+B.
Now add the shadow for the note border, select the note and create a wall shadow. I used a shadow blur of 3.6px and s transparency of 74% (flat); the
shadow position values are: X=-0.2pix Y=-0.4pix.
