Cutting Half-Square Triangles

 

One half of a diagonally cut square has the straight grain on both short sides adjacent to the 90° angle.

1.  After cutting squares remove the Speed Gauge and rotate the Cutting Guide left to 45°, taking care not to disturb the pieces on the Cutting Mat. 90angle
2.  Slide the Cutting Guide until the edge rests diagonally on one of the squares, touching opposite corners. Make the first cut along the side of the Cutting Guide. 45angle
3.  Slide the Cutting Guide to the next position, aligning the edge across the next square(s), and make the next cut. firstcut
4.  If you have moved the Cutting Guide from one side of the system to the other and still have triangles to cut, move the Cutting Guide to the Side Rail, then change the angle to the opposite 45° angle. 2cut
5.  Lift the knob on the Cutting Guide and slide the Head to align the Gutting Guide edge at the cut made in step 4. Note: Cut lines added for clarity. 3cut



Cutting Quarter-Square Triangles

Cutting setting triangles is a breeze with this system. This triangle has the straight of grain on the long side only.

1.  Cut half-square triangles following the directions above.  
2.  After cutting the half-square triangles, change the Cutting Guide to the opposite 45° angle. Remove the Side Rail if neccessary to make room. quarter1
3.  Slide the Cutting Guide into place with its edge lying across the half-square-triangle corners as shown. Lift the knob on the Cutting Guide when you move it so you won't disturb the pieces on the Cutting Mat. Cut the quarter-square triangles. quarter2
4.  Continue cutting quarter-square triangles until you have the desired number. quarter3


Cutting Equilateral Triangles

Each side of an equilateral triangle is the same length, and each angle is 60°. Use these triangles with hexagons for interesting quilt blocks.

1.  Cut the number of strips required.  
2.  Place the Cutting Guide on the Clamp Bar Rail and rotate to the left 60° position. To conserve fabric, offset the strips using the Cutting Guide for reference as shown. Place the Cutting Guide across the strips as shown and cut off the strip ends. equal1
3.  Slide the Cutting Guide to align the Speed Gauge with the first cut and make the next cut. Repeat by sliding the Cutting Guide and aligning the Speed Gauge to make as many cuts across the strips as you can. You have cut 60° diamonds from the strips. equal2
4.  Rotate the Cutting Guide to the opposite 60° position. Slide the Cutting Guide to align the edge of the cuts as shown. Cut across the strips. Repeat by sliding the Cutting Guide to make as many cuts as you need. equal3

Cutting Equilateral Triangles from one strip

1.  Align strip parallel to the Clamp Bar. Place the Cutting Guide on the Clamp Bar, rotate to the left 60° position and set the edge across the end of the strip. Make the first cut.

2.  Rotate the Cutting Guide to the opposite 60° position. Slide it to align with the top "point" of the strip as shown. Make the next cut.

3.  Rotate the Cutting Guide to the first 60° position and align with lower "point" of triangle as shown. Make the next cut.

4.  Repeat last two steps, cutting the number of triangles you need.
