I have noticed this problem with other brand new scarfs fresh even from the paper packaging. I think these pulls are created if the hemming needle used on the silk is not quite as sharp as it should be.
I personally won't settle for this given the price of an H- scarf, and so I always inspect the edges at the hem very carefully, even before I take the scarf home from the boutique. If I find any pulls, my SA just orders another one for me as she knows now that I won't except a scarf that has this issue.
With respect to the PdS, I did notice these pulls with the 1st scarf of cw01 I looked at AMS airport boutique, so I asked to see another one. The young SA said in a snotty voice that it was "prefect from the package, madame".... but when I pointed out this issue he was speechless.
Because this type of thing really bothers me, I've always been reluctant to order on-line - but fortunately the two scarfs I did buy from usa.hermes.com were fine. I hope you get this resolved to your satisfaction.
