Getting nowhere with this one (well, 8 clues after 4 days), and the prospect of an origami endgame isn't all that enticing as my scissors are blunt. I must have the wrong end of several sticks, but among the many helpful hints on here, it seems that the instruction, which I've assumed to be 33 incorrect letters in clue order, ends with 'en masse', and yet 29d and 31d both have an 'e' as the errant letter. Can someone please nudge me back towards the right track before I bin it. Thanks.
