You have to tell us whether you mean Polyester, of which Dacron is a
brand name, and is used for all sorts of running rigging, or
Polypropylene which is a much weaker rope, but which floats and is
used for water toys, etc. There is a huge difference in their ability
to hold knots.

Seems to me it's fair to assume he's asking about polypropylene, since
there'd be no reason to ask about polyester lines. In fact I see no reason
to even ask your question other than to demonstrate your knowledge of
chemistry.

Sorry, I had actually composed a response assuming polyprop and then
realized the ambiguity. Part of the problem, however, is that
nowadays the newer forms of polypropylene will hold a know rather
well, so to answer the question, one must know what type it is, and
what the application is.

For holding down a tarp, I'd throw away the presumably cheap, slippery
polyprop and go to the Home Depot where you can buy a lot of line that
will hold knot and is cheap enough to just chop away in the Spring.

Understood, but I have 600' of this stuff from Harbor Freight that was
given to me and finally have a use, hopefully, for it :-)

Just need a knot that'll hold.

I did a quick scan of rec.crafts.knots and my newer knot books by
Budworth - they all acknowledge the problem with polyprop but offer no
easy solutions. I've always added several extra hitches, and opened
the lay to tuck a generous tail through. A wrap with electrical tape
would work, and now that I think about it, a cable tie would probably
do a great job of securing a knot.

One of the reasons to read newgroups - I like that idea.

Thanks

Why not but a spool of the 'waxed whipping twine'?
It'll go a long ways and it's not too expensive.

Good question.

I just kept a spool of mason's twine and a hockey puck size piece of
bees wax in the ditty bag.

Got double duty from the mason's twine when it didn't have to be waxed.

Jeff,

Great idea on the cable tie. I think I'll use rolling hitches, with
elec. taped whipped ends and cable ties.

Thank you,
