Step-by-Step Sewing Instructions

Draft construction notes. Readable online; review against the pattern pieces before sewing.

1

Cut Canvas & Mark Tool Slots

Cut two main backing panels, one pocket strip, and one top protective flap from heavy canvas. Use chalk or fabric marker to mark vertical tool slot division lines (30 mm to 60 mm intervals) across the pocket strip.

2

Hem Pocket Strip & Foldover Flap

Double-fold and topstitch top edge of the pocket strip with heavy-duty thread. Double-fold and topstitch bottom and side edges of the protective foldover flap.

3

Stitch Tool Slot Divisions

Position pocket strip along lower edge of one main backing panel. Stitch vertical division lines through both layers, backstitching or bartacking securely at top pocket edge for strength under tool tension.

4

Attach Top Protective Flap

Position raw top edge of protective foldover flap along upper margin of the inner backing panel, facing down over the tool pockets. Baste in place.

5

Assemble Backing with Ties & Finish Perimeter

Baste folded tie straps to one side edge. Place outer canvas backing right sides together over prepared inner assembly. Stitch all four edges leaving an 8 cm opening. Clip corners, turn right side out, press, and topstitch entire perimeter 6 mm from edge, closing turning gap.

Troubleshooting & Fit Alterations

Solutions for common fitting hurdles and construction errors specific to this garment.

Problem: Seams puckering along stitch line

Possible Cause: Thread tension too high or needle blunt

Recommended Fix: Insert fresh needle and test balance on fabric scrap.

Problem: Wavy edge along curved perimeter

Possible Cause: Edge was stretched while feeding into machine

Recommended Fix: Staystitch immediately after cutting and use walking foot.
