The overhand knots are sliding and, while doing so, destroying the floss. Not good. That's why I don't want to do an overhand loop.
I'm sure the blood knot has plenty of use cases but why would I choose it over the zeppelin bend? Or, in this case where untying isn't needed, over the twistydore knot, which is way easier to tie quickly? I'm grateful and happy for the suggestions but I don't understand them, when they're clearly worse for this particular scenario. Use a binder clip to tie a blood knot, just for flossing? I was looking for something quicker/easier to tie than a zeppelin bend which I was using previously. Going the other way around, to a knot with
more fiddly steps, just seems absurd. I have to interpret it as you trying to fool me.
I want to respect knots. I don't want to be one of those who use a granny knot for everything. That also means using the knot that's
appropriate, not overkill, for the situation. I use a variant of a slipped surgeon's knot to tie my knee socks since that's just enough that they won't open by themselves, which they do with the regular shoelace knot. I use the zeppelin bend for various little things around the house. I do it because an appropriate knot that's not overkill is a beautiful thing. A thousand extra hitches and loops when they're not needed aren't.
I have never ever, until today, heard of reusing floss.
I searched for it and found this page:
Is it okay to reuse floss previously used?
http://answers.yahoo.com/question/index?qid=20090305181304AAxcUANMaybe there is some special kind of floss that can be reused. I haven't seen it.
It's weird, I haven't thought so much about it, maybe because it's guilt vs guilt - guilt over global warming vs guilt over not flossing.
I'll think about it, but I mean, I don't reuse tooth paste, either, right?
