Today I've started on the next batch of gowns - this time using a nice 38 mm ("heavy") silk crêpe.
I have used this fabric before, and have had the same experience before, too. Or - is it just something I am imagining?
One of the pieces looks approximately like this:
After cutting, I serge all the sides.
After serging, I sew the pieces together - and... I think the serging direction is of importance. Or am I just imagining things?
The warp direction is marked in blue. It is the same in all pieces.
There are two possible ways to do the serging - either from to top bottom (green), or from bottom to top (red).
I think that serging from bottom to top (red) stretches the bias, so it becomes longer than if I do the serging from top to bottom (green). The bias angle remains the same...
Or - am I just imagining things?
The difference is not bigger than it could be from the inaccuracies in the cutting... or?
