OK, I put in 1.75 hours today.

Pre-ironed in the box pleats and the reverse pleat...

Cut out the canvas waistband reinforcement strip, locked down the eges.

Aligned all the pleat overlaps at the waist and pinned the canvas strip in along the waistband in the back.

Stitched the canvas strip in, and stitched down the very tops of the pleats.

Cut out two strips of hair canvas (I'm out, now!) and locked down the edges.
Stitched in teh hair canvas, inside the over-apron and under-apron.

Put it on again and stared at myself in front of the full length mirror. It looks good. I'm glad I got this stuff and not the 8 ounce super-lightweight stuff from Sportkilt.

TOTAL: 8.75
