One might also consider cutting down 1/700 shrouds. I’ve done this before and the results are arguably better. Had I not on hand enough 1/1000 shrouds for 2 ships I would have gone the route of using 1/700 scale pieces. They’re extremely fine and with the fineness, the slightly wide spacing isn’t noticeable. My 1/900 Erebus and Terror were rigged with 1/700 shrouds. Had I not mentioned it, no one would have ever noticed.
