There was too much fullness in the canvas and I think the problem was that I was not tugging on the canvas when I was basting it with the forepart. The canvas had already been cut to shape the garment so I flipped it over and pressed the canvas to shrink it. That is when the creases on the garment appeared. Should not I have done that? would it have been fine to have the fullness on the canvas? if I run my hand through the canvas I would gather pleats at the basting stitches.
I have been sewing for a year and this is my first suit jacket that I have been making good progress watching the video series. However, it seems that a lot of the basic concepts I do seem to lack.
