Everyone, thanks so much for your help with my original question (and I’ve enjoyed the subsequent discussion, too). Just checking back in to let you know that the problem was, indeed, me tying the wrong knot. The standard bunny ears knot did the trick. Balfour-knight, I did find that other way of tying the knot on a YouTube video somewhere–basically a different way to end up with the same knot. Of course, I can’t find the video again. I remember it’s at the end of a video as kind of a “and here’s another way to tie that knot” p.s. Anyway … Thanks very much, everyone. Hope this will be helpful to some other harp parent out there.
