I've never carried dental floss in my kits before, but I'm thinking of adding some for general tying or lashing needs. I experimented with tying some knots and couldn't get them to hold. I was using standard waxed floss and I tried a square knot, a fisherman's knot (the one with the 2 overhand knots that slide up against each other) and a sheet bend with no luck. <br><br>Does anybody know of a few knots that work well with floss? Is the wax the problem?<br><br>
