1. For one block, gather a set of matching solid pieces (two 4-3/8" squares and five 2-1/4" squares) and a set of matching small or large print pieces (two 4-3/8" squares and four 2-1/4" squares).
2. Use a pencil to mark a diagonal line on wrong side of each solid 4-3/8" square.
3. Layer each marked solid square atop a small or large print 4-3/8" square. Sew each pair together with two seams, stitching 1/4" on each side of drawn line (Diagram 1).
4. Cut a pair apart on drawn line to make two triangle units (Diagram 1). Open triangle units and press seams toward print to make two triangle-squares. Each triangle-square should be 4" square including seam allowances. Repeat with remaining pair to make four matching triangle-squares total.
5. Sew together a solid 2-1/4" square and a small or large print 2-1/4" square to make a rectangle unit (Diagram 2). Press seam toward print. The rectangle unit should be 2-1/4x4" including seam allowances. Repeat to make four rectangle units total.
6. Referring to Diagram 3, lay out triangle-squares, rectangle units, and remaining solid 2-1/4" square in three rows. Sew together pieces in each row. Press seams toward rectangle units. Join rows to make a Churn Dash block. Press seams in one direction. The block should be 9-1/4" square including seam allowances.
7. Repeat steps 1–6 to make 12 Churn Dash blocks total.
