If making templates, include the 1/4" seam allowance on the template for machine-piecing. Place template on the wrong side of the fabric as for hand-piecing except butt pieces against one another when tracing.
Set machine on 2.5 or 12-15 stitches per inch. Join pieces as for hand-piecing for set-in seams; but for other straight seams, begin and end sewing at the end of the fabric patch sewn as shown in Figure 10. No backstitching is necessary when machine-stitching.
Figure 10 Begin machine-piecing at the end of the piece, not at the end of the seam.
Join units as for hand-piecing referring to the piecing diagrams where needed. Chain-piecing (Figure 11 - sewing several like units before sewing other units) saves time by eliminating beginning and ending stitches.
Figure 11 Units may be chain-pieced to save time.
When joining machine-pieced units, match seams against each other with seam allowances pressed in opposite directions to reduce bulk and make perfect matching of seams possible (Figure 12).
Figure 12 Sew machine-piecing units with seams pressed in opposite directions.
