Whipping the ends would obviously not be for life support.
(i.e. it's
not for monitoring & keeping a splice in place.)
It's just to keep the rope from fraying & dress.
Therefore, it doesn't need to be splicing quality, polyester whipping twine.
Several suggestions:
Contact "JoAnn Fabrics", & other sewing stores, etc.
Upholstery repair shop (they would need to frequently color match)

(looks like purple to me ............... ;-)
If you want it to be tacky (like normal whipping twine), draw it thru a small chuck of bee's wax.

"This is a product called whipping twine and it is used to wrap the ends of rope to keep them from becoming unraveled. The whipping twine is unique because it is waxed and comes in some real nice standout colors. The wax on the twine provides two big benefits. First, it allows the twine to pass through the rope nice and smooth, and secondly, the wax on the twine allows the final whipped assembly to sort of "weld" together and hold tight when you are done.
This is some real nice stuff, the best we have seen. "
- 6 color choices - Red - Blue - Green - Gold - Black - White
- 134 feet on a spool
- This size is best for ropes in the 3/8 to 3/4 range. Anything bigger would need either a #8 or #16 twine.
If you are going to be whipping arborist ropes (like the 16 or 24 strand rope) then this is the whipping twine to use.
