No wonder you are up late ;*). 

I too have tried masking a stereo slide pair individually, but 
without great success. 

If you_do_ want to do it, film strip-leader seems a reasonable material to 
use in place of paper - it is dense, flat, easy to cut straight, and has 
no peculiar problems in viewing or in projection.:) Keep those bits of 
totally exposed film - they have all sorts of uses! (eg I have a film for   
                                              testing camera wind-on's)

I see the masking/cropping problem in stereo as being really one of 
modifying the 'Window' rather than the image. This actually makes it 
easier. 
If the image is mounted in a foil mount (I use Albions), then a second 
foil (the 'masking foil') can be placed over the first. Slide it 
horizontally to make the 'window' narrower, and vertically to 'letterbox' 
it. Trim overlapping edge of 'masking foil' as required. Bind mount as 
usual. Job done.

This method ensures equal masking of the left and right image, avoiding 
the potential problem of the depth of one side of the window being 
different from the other. It is also very straightforward - but perhaps 
only for foil mounts.  With a little more work it may be possible to use 
the ready-made-window quality of foil mounts to serve as masks in 
RBT mounts? 

What sort of mount are you using?
