Assemble and Add the Triangle-Square Border
1. Use a quilter's pencil to mark a diagonal line on the wrong side of the cream print 3-7/8-inch squares. (To prevent the fabric from stretching as you draw the lines, place 220-grit sandpaper under the squares.
2. Layer a marked cream print 3-7/8-inch square atop each red or pink print 3-7/8-inch square. Sew each pair together with two seams, stitching 1/4-inch on each side of the drawn line (see Diagram 2).
3. To save time, chain-piece the layered squares. To chain-piece, machine-sew the pairs together one after the other without lifting the presser foot or clipping threads between pairs. First sew along one side of the drawn lines, then turn the group of pairs around and sew along the other side of the lines (see Diagram 3). Remove the chain-pieced pairs from the sewing machine and clip the connecting threads.
4. Cut each pair apart on the drawn line to make two triangle units (see Diagram 4). Press each triangle unit open to make a triangle-square (see Diagram 5) for a total of 56 triangle-squares. Each triangle-square should measure 3-1/2 inches square, including the seam allowances.
5. Referring to the Quilt Assembly Diagram for placement, sew together 13 triangle-squares to make the top pieced border strip. Note the two directions of the triangle-square seams. Press the seam allowances in one direction. The top pieced border strip should measure 3-1/2x39-1/2 inches, including the seam allowances. Repeat to make the bottom pieced border strip. Sew the pieced border strips to the top and bottom edges of the pieced quilt center. Press the seam allowances toward the border.
6. Sew together 15 triangle-squares to make the left-hand pieced border strip, again noting the two directions of the triangle-square seams. Press the seam allowances in one direction. Add a Nine-Patch block to each end of the left-hand pieced border strip. Press the seam allowances toward the triangle-squares. The pieced border strip should measure 3-1/2 x 51-1/2 inches, including the seam allowances. Repeat to make the right-hand pieced border strip. Sew the pieced border strips to the corresponding edges of the pieced quilt center to complete the quilt top. Press the seam allowances toward the border.
