I just wanted to share what ive done so far i started working on this pattern well before Rory released the series so i didnt want it to go to waste. so far i have mark stitched the fore part and assembled one canvas. I didnt have enough canvas to make the suit full canvas so i decided half canvas will do i dont know if that changes anything but ill probably have to add some interfacing down the center front and maybe on the hem. I opted for patch pockets which is why there is no welt on the dart
/ update I sewed the straight seams and the darts
Attached first patch pocket with pickstiches for top stitching (pictures)right and wrong sides. My handwork is pretty bad lol but im getting better
Pull lines on fabric are from pulling the stitches too tight
Thats good news . The next one will definitely be full canvas.
There was a tailor in Dublin used to use the method. You still get the roll on the lapels which is good.
I only ever do a half canvas these days. Basically, I do only a chest piece with haircloth and domette/felt. I put fusible interfacing on the entire front piece. It's similar to what I've seen on many factory garments. I find the results quite satisfactory.
