I've just scanned thru the silk section in Mark Wilson, but right enough there's nothing about that effect. I'm not quite sure how I'd do it tho perhaps if you had the right clothes you couls start at yorr deasired sleeve end, up to just before shoulder and back down and up giving 3 arm lenghts with no tangle risk so far, then you could go down and up both legs haha but it might get a bit awkward tugging at it, but worth some experimentation I guess, off the top of my hea, you get another 3 arms length before you did the trousers on the opposite arm maybe.
Perhaps if you concealed the whole spool inside a jacket lining you could access to replace it you could perhaps make it spin relatively freely on a small dowel or something thru the middle...maybe easier still if you intend a well behave audience member to tug at it
I've had to tamper with a few items of clothing over the years, it's really satisfying when you nail it haha.
