From Color 3:
- 4 – 3-7/8″ squares (cut each in half diagonally for 8 medium triangles)
Assembly Steps:
Sew together one color 2 small triangle and one color 1 small triangle along short sides (Diagram 1). Then join the long side of a color 1 medium triangle to the color 2-and-color 1 triangle set. Repeat to make a total of four units.

Diagram 1
Sew together the Step 1 units in pairs. Press the seam allowances in opposite directions. Then join the pairs to make the center unit.
Sew the long side of a color 3 medium triangle to one short side of a color 1 large triangle (Diagram 2). Repeat with a second color 3 medium triangle on the other short side of the color 1 large triangle to make a Flying Geese unit. Press all seam allowances toward the color 3 triangles. The Flying Geese unit should measure 3-1/2 ×6-1/2″, including the seam allowances. Repeat to make a total of four Flying Geese units.

Diagram 2
Lay out the pieces for one block in horizontal rows (Diagram 3). Sew together the pieces in each row. Press the seam allowances toward the color 1, 3-1/2″ squares, or the center unit. Then join the rows to make a block (Block Assembly Diagram). Press the seam allowances in one direction.
