The red 'escape' measures 5cms by 2cms:
And another interesting use with the transparent plastic is that you can have stitches beneath it, worked directly onto the background fabric, which still show through: this way, part of the background can be given a 'shine' (I think it looks a little like the shadow on the 'A'is underwater). Solid metal threads obviously do not have this potential. And in the right direct light, the plastic really shines, 'illuminating' it.
Blue stitched area 2.5cm by 2.3cms:
The next one was worked onto cotton organza (which is the most transparent fabric I could find). Unfortunately, unlike the organdie I've been sticking to as of late, it's just too fine for this sort of stitch: the slightest pull, the slightest over-tensioning of the stitch as it's worked, and the organza will just rip. I got away with it here due to excessive patience but practically, it could 'run' and spoil far too easily.
But feeling inspired by my persistently patient approach to the sample above, I took an A4 plastic wallet, chopped a section out and started stitching onto that too. It spells out 'nothing' but didn't especially need to be done to completion:
There's some even stranger stuff following shortly in another post.
