Hi, Alan. Below are a few comments on the angling knots.
1) The Palomar knot has been presented in three forms:
<a> as you've shown, with the bight end around the hook;
<b> as Sosin & Kreh specifiy, with this bight slid back around
the knot body;
<c> as Budworth has shown, with the bight up around the SPart
(sort of Pile-hitch-like).
I'd go with <b>, as those guys actually fish(ed).
2) You show the Blood knot in what Barnes calls "outcoil" form,
and it is best shown (and tied) incoil--the wraps beginning at
each end and working towards the tuck in the center
--which in any case IS the form that the knot will assume under
tensioning, in common materials used in angling.
3) To assert that "The Double Surgeon's Knot can only be tied ..."
is going too far: any knot can be tied with ends, though in this
case, with fiddly fine & springy fishline it would be a bother.
Better is "The <DSK> is tied with ... , as the ... IS passed ..."
4) It seems that the material you've used is chosen for presentation
aspects (distinct colors!), but isn't so much like common angling
materials. Thus, some of (most of ... ?) your knots aren't set in the
form one should expect in the field--e.g., the Dble.Surg. Loop
should be symmetric, with the extra turn spilling into a lone wrap
around the knot body (as in the Grapevine, Strangle).
You might be able to coerce such forms in your material?!
<5> Now, as for what actually happens with the Uni Knot,
I"m still unsure--it is a form of multi-overhand, but ... .
Thanks,
