Wrap of Carapacian Cloth (3)

Has anyone else produced this on the textiles station? I was churning out bolts of cloth, suddenly noticed this was sat on the station. I was chopping between the game window and internet browser at the time so not even sure how it happened there's no recipe in my book for it, so I can only imagine it's an occasional 'upgrade' to the normal product, rather than something you intentionally craft.

Edit: scratch that, just done it again with fustian and realised that 'wrap' is actually a 'strap' in the recipe book... never mind
