Last bit of work for the evening.

Worked up one of the flaps for side vents. Used fabric cut from the front of jacket, as it was size needed and already had some nice pressed/hemmed edges. Fabric doesn't have a "twill" or similar weave that I can see, so it doesn't matter that these little pieces are going to sit 90 degrees from their original orientation. Here is one piece next to its vent.


Pinned in place, right sides together. I've lined up the pre-hemmed bottom edge of flap just slightly higher than jacket hem, so the flap won't droop beneath the jacket. I'll start stitching precisely at the top of the vent. I have already opened up this seam allowance and reinforced the stitching where the vent ends and the side seam begins.


Plunging the machine needle in just at the top of the vent. Note that the free side of vent (green-headed pin) is folded out of the stitching line, so it won't get caught up.


Flap stitched in place (there's that green pin again).


Vent flap laid flat, over the flap.


Some vented jackets have a visible line of stitching that runs from the top of the vent, at an angle, toward the "flap" side of jacket. This anchors the top of the flap and helps reinforce the area. I didn't want a visible line of stitching, so I unfolded the seam and stitched only the seam allowance to the flap, beginning at the top of the vent and angling upward. Once I get the lining tacked down in this area, I think it will be robust enough for the application -- dancing yes, caber tossing maybe not!

Then I hand-sewed the lining to the pressed, curved cutaway front jacket edges. Don't know where that photo went! But I'll continue the saga tomorrow. Thanks for coming along for the ride so far!
