Half Square Triangle UnitsHalf square triangle units are used to create definition for the Scottie Dog's head and tail.
- Pair a 2-7/8" x 2-7/8" background square with a gray square of the same size. Use my easy sandwich method to sew the squares together, creating two half-square triangle units. Each completed unit should measure 2-1/2" x 2-1/2".
- Make four more half square triangle units by pairing two 2-7/8" x 2-7/8" background squares with same-sized gray squares.
- Make two half square triangle units by pairing the 3-1/4" x 3-1/4" background square with a gray square of the same size. The unit should measure 2-7/8" square.
Quarter Square Triangle UnitQuarter square triangle units aren't difficult to make, and quick-piecing allows you to construct them without handling small triangles. Before you begin, read through my Quarter-Square Triangle Instructions to get a feel for the basics.
- Find a half square triangle unit made from 3-1/4" squares.
- Draw a line from one corner to an opposite corner on the reverse side of a 2-7/8" gray square.
- Pair the plain square with the half square triangle unit, right sides together and aligned so that the marked line is perpendicular to the triangle square's seam.
- Sew a seam 1/4" on either side of the line, just as you did to construct the half square triangle unit. Cut on the marked line and press the quarter square units.
- Units are mirror images of each other. Refer to the illustration to see which one is used for the right-facing Scottie. The remaining unit can be used to sew a left-facing dog.
