Dark for centers (Can be same as above)                                  ½ yard          Cut: 20,  4½-inch squares
Medium Light for triangles inside star                                      ½ yard          Cut: 20,  5½-inch squares
Light for outside triangle of hourglass blocks                          ½ yard          Cut: 20,  5½-inch squares
Same light fabric for 1/2 of half-square triangles                      1 yard          Cut: 40,  5-inch blocks
Medium fabric or fabrics for 1/2 of half-square triangles        1 yard          Cut: 40,  5-inch blocks

 

Instructions

  1. Place the 5-inch blocks, right sides together, with the light on the top. Draw a diagonal line from upper left corner to lower right corner.   Sew a scant ¼ inch on each side of the line by chain piecing. Cut on the line. Press toward the dark fabric. Trim each resulting half-square triangle to exactly 4½ inches square, with the diagonal in two corners.
  2. Place 20 of the Dark 5½-inch squares right side up, and place the 20 Medium Light 5½-inch squares right side down on them. Draw a diagonal line from upper left corner to lower right corner.   Sew a scant ¼ inch on each side of the line by chain piecing. Cut on the line. Press toward the dark fabric.
  3. Place 20 of the Dark 5½-inch squares right side up, and place the 20 Light 5½-inch squares right side down on them. Draw a diagonal line from upper left corner to lower right corner.   Sew a scant ¼ inch on each side of the line by chain piecing. Cut on the line. Press toward the dark fabric.
  4. Place 1 each of 2. & 3. above, right sides together, Dark against Light and Medium, butting the seams together, and draw a line from the corners not in the seam. Pin at the seam and end of the line. Chain piece, ¼ inch from the line on both sides of the line.   Cut on the line. Press open. Trim each resulting hourglass block (quarter-square triangle) to exactly 4½ inches square with the seams at the corners.  (Look twice through the 6″ square, clear acrylic ruler.)
  5. Lay out on a design wall or bed.   Assemble the blocks in rows, then sew together. Press first row to left, next to right, down the rows.   Sew rows together, and press up or down.
  6. Add borders to desired size, if you wish.   Can be quilted in the ditch in 4 directions, from the center out, horizontally and vertically, and in 4 directions, from the center out to each corner diagonally, with one thread color, the same as the “trellis” (light background).
