Understanding Materials

and Measurements
Here are the two “M”s of cordage
for projects in this book: material
and measurements.
These are the materials I used
to make different projects in this
book:
> I use cotton in the seine twine
and cotton rope projects,
including net knot bags
1 ⁄2 inch #72 (Chapter 5), monkey’s fist proj-
ects (Chapter 4), and square
3 ⁄8 inch #60 knot projects (Chapter 2).
> I use manila (also called abaca)
#48
1 ⁄4 inch in doormats (Chapter 7).
#36
> I use cotton rope for the
#30 companionway stair treads
(Chapter 7).
#24 > I use rayon and leather to

#18 make the knotted jewelry in
Chapter 10.

1 ⁄2 inch 3 ⁄8 inch 1 ⁄4 inch #72 #60 #48 #36 #30 #24 #18

Thinner cotton seine twine is measured by the number of threads it contains. Shown here is cotton seine twine from #18
up to #72. Thicker cotton rope is measured in inches, shown here from ¼ inch up to ½ inch.
