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.
