1. Fold each solid white 12" square in half diagonally twice. Lightly finger-press each fold to create 20 foundation squares with appliqué placement guidelines; unfold.
2. Referring to Appliqué Placement Diagram, lay out four 4"-long stem appliqués and sixteen 1930s print buds on each solid white foundation square; pin or glue-baste in place.
3. Using clear monofilament thread and working from bottom layer to top, machine-zigzag-stitch around each appliqué to make 20 appliquéd blocks.
4. Soak appliquéd blocks in cold water to remove starch. Machine-dry with dry towel to help absorb excess water. Trim excess foundation fabric from behind appliqués, leaving 1⁄4" seam allowances. Press each block from wrong side and trim to 11-1⁄2" square including seam allowances.
