Assemble the Block
1. Position the A and B appliqué pieces on the solid white and solid red triangles to make four white triangle units and four red triangle units (Unit Placement Diagram).
2. Using small slip stitches and threads that match the appliqué fabrics, appliqué the curved edges in place on each unit. Baste along the straight edges within the seam allowances.
3. Sew together the units in pairs to make four quadrants.
4. Referring to the Appliqué Placement Diagram, sew together the quadrants in pairs. Press the seam allowances in opposite directions. Then join the pairs to make a block. Press the seam allowance in one direction.
