Challenge: Instructions for Tying Wrap Knots on a Bight

[knot4u]

For knot nerds out there who like making instructional videos or pics, here's a challenge.  Make short videos on how to tie wrap knots on a bight.  Even better are pics/diagrams because videos are less accessible.  I may get around to it one of these days after I get better at tying knots on a bight!

Here are some wrap hitches/binders that can be tied on a bight:

Bag (ABOK #1244)
Constrictor
Double Constrictor
Boa
Clove
Munter
Pile
Double Pile
Sailor
Snuggle

The challenge is finding a memorable technique for each knot.  If I forgot any useful knots that are tie-able in a bight, then here's the thread to list some more!

Tying a knot on a bight has value in many applications.  Examples include tying a binder around a bag opening, hitching or binding by using the middle of a long rope, where you have no access to the tip of the working end, or anywhere else tying the knot the conventional way is less convenient.

I like the coil-twist-fold method for both the Constrictor Knot and the Boa Knot:

Tying a knot on a bight has value in many applications.
Examples include tying a binder around a bag opening, ...

I'd say that this is a case where --often, at least-- one does
NOT want to form the binder in the bight, as that would
entail consuming much material to amply open the binding
to accept the bag before tightening it; whereas if one can
begin with a short end, then work the rest around to close
quickly, the material can be cut off to leave only another
short end (and not two long ones).  The ground-line hitch
is a miller's knot that can be so formed; the casting a half-hitch
around the bag opening is usually easily & quickly done and
drawn tight.
