Fabric Cutting and Preparation
Lay Out Your Pattern Pieces
Arrange the pattern pieces according to the cutting layout diagrams. Begin by positioning the pieces on the fabric, ensuring that the grainline arrow runs parallel to the selvage.
Cut Your Fabric
If you are using fabric shears, trace the pattern pieces and then cut them out, cutting away any pen, pencil, or chalk lines. Remember to cut out any notches that appear on the edges. These markings help line up the pieces when you assemble the garment.
Transfer Pattern Markings
Use your marking pen, pencil, or chalk to transfer the markings to the wrong side of the fabric. Mark the center front of pieces cut on the fold to help align pieces accurately during construction.
Seam Allowance
Please follow the seam allowances as indicated on the pattern file layers. These are provided specifically for each piece to ensure accurate construction.
This pattern uses a 1.1 cm (or 0.45 inch) seam allowance all around, 2.54 cm (or 1 inch) at the hem and 2.54 cm (or 1 inch) at the slit.
