To make a template of a specific pattern, lay template plastic over the pattern and use a ruler and permanent marker to trace the solid outside edges, dashed seam lines, and grain-line arrow onto the plastic. (An arrow on a pattern indicates the direction the fabric grain should run.) Mark the template with its project name, letter, and any marked matching points.
Cut out the template and check it against the original pattern for accuracy. If it isn’t accurate, the error (even if it’s small) will multiply as you assemble a project.
Using a pushpin, make a hole in the template at all marked matching points. The hole must be large enough to accommodate a pencil point.
To trace the template on fabric, use a pencil, white dressmaker’s pencil, chalk, or a special fabric marker that makes a thin, accurate line. Don’t use a ballpoint or ink pen, which might bleed. Test marking tools on a fabric scrap before using them. Place your fabric right side down on 220-grit sandpaper to prevent the fabric from stretching as you trace. Place the template facedown on the wrong side of the fabric with the template’s grain line (or one straight edge of the template) parallel to the fabric’s lengthwise or crosswise grain. Trace around the template. Mark any matching points through the holes in the template. (When sewing pieces together, line up and pin through matching points to ensure accurate assembly.)
Repeat to trace the number of pieces needed, positioning the tracings without space between them. Use scissors or a rotary cutter and ruler to precisely cut fabric pieces on the drawn lines.
