2) Angle Line Markers
Guidelines'
Angle Line Markers are used to highlight
any of the individual angle lines on the
bottom of the Ruler. It’s a pretty
simple idea, but we are always amazed at
how many quilters have a ruler with angle
lines, yet still buy 2 or 3 special angle
rulers.
We say, highlight the line you need
with these Angle Line Markers, and it’s
just like having a special ruler just for
angels. Let’s
use them to make some equilateral triangles.
They are
held in by friction and can be removed
by sliding your fingernail underneath
the edge of the marker. 
Example of making equilateral
triangles:
Equilateral
triangles are made using the 60 degree
angle lines on Guidelines. You’ll be
using both 60 degree lines to make them.
You can choose to put both Angle Line
Markers on one line or one on each line.
Either way you’ll
be able to clearly see which lines you
should be using. We
recommend in this case, however using
each Angle Line Marker on each line, so
you don't have to switch the Markers
from one line to the other every time.
First, cut a strip.
With each
Angle Line Marker placed on each 60
degree angle line, line one of the angle
lines up to the edge of the
fabric. Hold it in place, and cut along
the edge of the Ruler. You’ve now
created one 60 degree angle and a triangle
as shown on the image on top. You don't
need this triangle.
Let's
create the other side next. Simply turn Guidelines,
so that you can line the other 60 degree
line up to the edge of the fabric, creating
a complimentary 60 degree angle. Line it
up, so the edge of the Ruler you’ll
be cutting on crosses the tip of the angle
that you just cut. Then, hold it in place
and cut again. The piece that you just cut
off will be an equilateral triangle. You
can continue rotating from one angle line
to the other to make as many equilateral
triangles as you need.
Diamonds,
Equilateral Triangles, Parallelograms,
Trapezoids and other common quilt pieces
can be made using the three angle lines
on Guidelines: 30, 45 and 60 degree lines.
With its Fabric Guides and Angle Line Markers,
Guidelines makes it easy to make them all.
