needle brands are not something we've
spent much time on, " he says.
Goodyear uses SAN 5 or SAN 6 needles
for nearly every job. " They're versatile
and reliable, " he says. " And since we
use PTFE thread on most projects, our
needle and thread setup doesn't change
that often. [However] materials such as
polycarbonate require larger needles
with a tripoint tip. These needles are
designed to punch and remove material
while sewing, allowing the thread to pass
through easily. "
Threads up their game
Patterson also favors PTFE thread for his
marine projects, using 2000 denier 3T
for general seams and 2700 denier 3T
for decorative topstitching. The PTFE
threads he uses are expensive but they
perform well with his sewing machines,
an important consideration, he says.
" They don't all sew the same, " he

redesign of this 340 Sundancer craft. It used a
CNC-created hexagon pattern and applied
that as an accent design for the project.

Aruvo thread from Fil-Tec was introduced a
few years ago. The thread has a multifi lament
construction that makes it easy to use, with
a sewing behavior similar to any standard
marine or outdoor application thread. It is
resistant to harsh weather, UV rays, chemicals,
rot and mildew and comes with a limited
lifetime warranty. Photo: Fil-Tec Inc.
Weaver Canvas offers a full range of
custom and OEM marine upholstery,
canvas and boating products like bimini
tops, enclosures, covers, cushions and
more, says Chris Patterson, owner of
the Wilmington, N.C., company.
He started the business in 2002, using
the same needles as the previous owner.
The company has experienced very few
needle problems, Patterson says, adding
he purchases " high-quality " needles from
sewing machine suppliers, using size 18
for vinyl upholstery, size 20 for clear vinyl
and canvas, and size 22DP for polycarbonate
enclosures. Because things
have gone fairly smoothly, " needles and

says of threads. " We've tried different
ones and have had trouble getting the
machines adjusted to sew nicely with
some of them. "
Goodyear says he uses PTFE threads
for 95 percent of his work because of
their high UV resistance and the fact that
they won't rot or weather-why he considers
them " lifetime threads. " However,
he does sometimes use polyester threads,
citing their strength and affordability.
" PTFE thread costs about fi ve times as
much as polyester and these costs can
add up, " he says. Although polyester
threads will break down over time from
UV exposure, requiring restitching, these
can be a good option for the boat's interior
where UV exposure isn't an issue.
" We use PTFE thread for upholstery
as well, but the thread must be round, "
Goodyear adds. " Certain brands of
PTFE threads are square shaped when
viewed microscopically. These types
of threads shouldn't be used because
they'll actually cut the material over
time, causing seam failure. "
