10 mm (3/8 in) included on all seams.
15 mm (5/8 in) double-fold hem.
6 mm (1/4 in) for neckband or binding attachment.
Press fabric before cutting to remove packing folds and pre-shrink fibers.
Align piece grainlines strictly parallel to fabric selvages.
Transfer notch markings with small 3 mm snips into the seam allowance margin.
Print Page 1 at 100% scale without page scaling. Check Metric box (50 mm x 50 mm) or Imperial box (2.0 in x 2.0 in = 50.8 mm) with a rigid ruler.
Align numbered registration marks and butt tile edges flush without overlapping untrimmed paper. Tape securely.
Transfer the two horizontal reinforcement guides and the lower work-zone marking to the Apron Main Body. Stitch the reinforcement rows through the marked area with heavy-duty thread, keeping both rows parallel and backstitching securely at their ends.
Turn the side and lower edges to the wrong side in two narrow folds, pressing each section before stitching. At the curved bib transitions, ease the inner fold so the finished edge lies flat and remains strong under work use.
Double-fold and stitch the upper edges of the Bib Patch Pocket and Divided Tool Waist Pocket. Press the side and lower allowances under, then transfer the printed pocket divisions and reinforcement points.
Place each pocket on its printed outline and topstitch the perimeter with two parallel rows. Stitch the tool-pocket divisions and add bartacks at every opening and at the marked high-stress lower reinforcement area.
Finish the Cross-Back Straps and confirm equal length. Place the strap ends right sides together at the upper bib corners, stitch, turn them upward, and secure each end with a Box-X plus a second horizontal reinforcement row.
Thread tension too high or needle blunt
Insert fresh needle and test balance on fabric scrap.
Edge was stretched while feeding into machine
Staystitch immediately after cutting and use walking foot.
