I own a fair number of old patterns and a lot of old sewing books. So I decided to do some research and share my findings with you!
But I do like the floating scissors in this illustration. So clear!
Still no interfacing used, even though they both tell you to make bound buttonholes down the front. I found that so hard to believe ... BOUND BUTTONHOLES in one layer of cotton fabric???
The interfacing was assembled separately, basted to the garment pieces, then the facing (which had no interfacing) was sewn on. The reason it was done this way was to prevent the shadow of the seam allowance showing to the outside. The interfacing sewn this way gives an extra layer of fabric between the outer fabric and the seam. When the interfacing is applied to the facing instead, the seam allowance is right next to the outer fabric and therefore it is more likely that a shadow or ridge of that seam allowance will show on the outside, especially after pressing.
This seems to be the be change over. The one on the left ... no interfacing. The one on right INTERFACING! But done this way.
It became clear that, if you are going to use fusible interfacing for a neckline or armhole, it needs to be fused to the interfacing NOT the garment, because there will be a clear ridge visible from the outside where the edge of the interface stops.
So, that is how we got to where we are today. I believe pattern companies were trying to keep home sewing simple at first without interfacing. Simplicity holding on the the simpler method for the longest. Then, to give more professional results, they introduced interfacing using the custom sewing method, applying it to the garment first. But, then when fusible interfacing appeared on the scene, the interfacing needed to be applied to the facing instead to avoid an interfacing "shadow".
Please tell me who this man is?
She is not in a professional sewing studio. This is supposed to be her home. So, is he her husband?? The next door neighbor? The mail man??? WHO? What man from this time would sit on the floor and pin a hem, anyway!
OK ... this is an update to this blog I'm writing on Sunday, 4 days after the original posting and ...
Well, I stand corrected!! after reading the comments below ...
See, my father would NEVER have sat on the floor and hemmed any of our skirts. But I had 3 sisters, so there was never a shortage of people who could and would make a hem in my home!
Thanks for all the comments!
