For instance, I have found that when setting up rad barrier rope that may be expanded or shrunk repeatedly for storage of RAM, a knot called the tauntline knot is invaluable. This knot will stay where you place it and yet can be slipped along the rope run easily to shorten or lenghten the distance of a boundary.
Another good knot to know is a 'self-cinching' bow knot...this will keep your modesty garments from falling down under your PCs...
Same basic knot as you use to tie your shoes (I got it out of a knot book that recommends it for that purpose), except, with the basic knot, the process is :
1. Tie the laces together.
2. Make a loop out of one lace.
3. Wrap the other lace around the loop and tuck this lace back thru the wrap you just made.
(Look familiar? Hard to put in words what I do without thinking...)
Anyway, the 'self-cinching' version is the same EXCEPT :
3. Wrap the other lace around the loop TWICE and tuck this lace back thru the WRAPS you just made.
Give this a try (on your shoes OR modesties) and let me know if I made the instructions clear enough to follow.
PS. Hey SloGlo...how do I make a tautline hitch? I used to know, but lost my book. :/
