Hi Rory, do you always sew your outbreast/chest pocket first before canvassing? So it means it is not to sew with/thru the canvass?

@Kunsthandwerk It was a mistake. I don't have any idea what those arrows for. Now I know, my bad.

Just a quick comment on my original question, I think it is also easier and quicker to not stitch the outbreast on the canvass. The only thing I am concern when you use pocket squares it shows that it is on top of the body canvas and pocket bag of the outbreast tends to show specially if you are dealing with lighter fabric like super 160's and above.
