Now to tie the shock cord to the fishing snap swivel. I have two choices for the knot. The figure 8 follow through knot and the anchor hitch. Trying to decide which one to use. Don’t want knot coming undone.

I've been using a double bowline knot because it is simple for me to remember and I put a small dab of yellow glue on the knot to secure it.
Some lines knot easier than others- it seems to me that kevlar doesn't knot very well. If you search the internet you find a lot of knots, some that are stated to work well with slippery line. I've found some knots that look good but I can't remember them so I go back to the knot that I can remember and put the dab of glue on it.

I just use a bowline knot. Then I use wood glue to hold the lines in place.
Sometimes I'll follow the bowline knot with 2 overhand knots.

Just learned how to tie that knot, thanks!
Went with the anchor hitch and a big dot of wood glue.
Haven’t even flown it yet and shock cord is tangled. Sigh.
@bjphoenix My bowline knots, even the double kind, seem to slip up and down on the standing end of the string. Is that what the knot is supposed to do?

Braid the cord as per Tim's video. This works great for all sizes of cords from the small #60 Kevlar up past 1" wide Nylon.
Not only does this prevent tangles but also absorbs energy reducing shock to the recovery system.

It's not the kind of knot that could slip. But with Kevlar it could untie itself, at least the standard Bowline can.
I must be tying it incorrectly. I will find a different knots website and practice some more.
I can send you a scan of my Boy Scout Handbook and a video, it was a First Class rank requirement.
That’s Ok. Thanks for the offer. I will get the hang of this.
Here is my bowline knot tied with 50 pound polyester kite line. I can tighten the knot, but the knot just pops open. It loosens itself.
I must be misunderstanding something about a step in tying this knot.
If I try to tighten it, it does this:
Maybe it is the super slippery line. I am going to try this with a different kind of string.

I think you are.
When I tie it with 100 or 300 pound kevlar, it loosens up slightly over time (without glue to hold it in place), but it doesn't unravel.

I have been using the 'figure 8' knot on Kevlar. Been working well.
@smstachwick
OK. Here is the bowline tied using 120 pound dacron polyester kite line. It holds.
Hmm. Maybe the super slippery 50 pound line is just bad for tying knots?
I can get the figure 8 knot to tie in a variety of line types. I like it too.
Bowline tied in 100 pound braided kevlar. No problems.
Ok. I now officially exonerate myself amd blame the weird, slippery kite line for my problems tying the bowline knot.

Wait! I just tied a nice, tight double bowline using the suspect string.
It WAS me after all!
The secret for me was laying the cord on a flat surface while I tie the knot, so I can see the shape of each step.

That first one looks a bit like a sheet bend. It’s a close relative of the bowline and is tied similarly but is mainly used to join lines of different thicknesses together instead of creating a loop.
Difficult to tell without clearly seeing which part is the excess, though.
For reference, I don’t think you’ll find a much clearer diagram and picture than these. If yours looked like these at any point, I’d call it safe to pin it on the line.

Since we're talking about the bowline knot, how do you all pronounce it?
Bow-line?
or
Bow-lean?

My undestanding is that the figure 8 is better than the bowline for these applications. I just don't use it b/c it's harder for me to tie (and remember how to tie).
Bow-lin.
It’s that British maritime accent. You know, like boatswain is pronounced “bosun”. Go figure.
Bow as in bow and arrow.
“Line” pronounced like the name, “Lynn”. Loretta Lynn.
Bow-lin.
Looking at these images it seems that I've been doing the bowline wrong! I learned it almost 50 years ago when I was doing a lot of fishing and haven't used it since, until I started tying kevlar last year. Apparently I remembered it slightly differently. Now I have to compare both versions to see how they compare.
What I'm doing wrong- in step 1. the cord end goes through the loop from the back, I was doing it from the front, with everything else the same.
Just learned a new knot. The Palomar knot. Very handy for tying onto snap swivel.
