Isn't it amazing how a delicate almost weightless thing can cause so much consternation! It's always the way.
Holly - thanks for the comment and compliment. You are exactly right
about the weight. I have
yet to get a light enough French seam to hang well, and even a seam with
too much edge stitching (either over lock or serger) is too heavy. This
is what works the best on my dresses, skirts and long trains which are long and much heavier seams than blouses our dresses. I've even been known to sew these
by hand - usually when they are lined or faced. This may not be very cost-effective, but the most important thing here is that the finished garment hand and look straight.
Here are a couple of photos
This one (above) shows the seam hanging - it's just as straight and unwobbly as a seam like this can get.
This
one (above) is a more detailed photo - click on image and you can see the light stitching. The stitching is fairly far apart, making it less thread per inch, making it more light-weight.
A lot of folks have told me that this is not being money wise about my time. I tell them, I have a fabulous reputation today because people know this is the quality of work I turn out. If it takes me doing it by hand, so be it.
Here again are my rules (the "not by hand rules!"):
- The seam, technique or thread (or amount of thread per inch) can't weigh a lot
- The seam can't buckle, wobble, wrinkle or crinkle at all - what I call easing in a lot of fabric into a short space. I lay it on a flat surface to match the seams as closely as possible, and pin about every 6" like this: When you sew on the edge (or serge on the edge as I do, then the pin does not interfere with the needle or any other mechanism and yet the fabric remains tacked and in place while the sewing occurs.
- The seam has to sew in just as the machine will feed it. This means that there's no pulling or stretching or pushing involved, that you might otherwise be able to get away with in another fiber or fabric.
For me, this comes down to a clean seam. I don't care how it looks coming out of the machine or after I've pressed it. What counts is how it hangs on my client. If the seam is straight on my client, that is what matters. Even in some of the beautiful designer hand-made garments that I have altered in chiffon, the seams are done very lightly and very delicately - some are just sewn with no over-stitching on the edge at all.
Now, here's the joke. I remember once I was going through a particularly hard learning curve on a lapel on a jacket once with my mentor teacher. She had me taking that dang thing in and out about 5 times, I swear. I had put in the collar backwards, and she wanted me to take the collar out of a notched lapel of a tailored jacket after I had done all that hand work to get the interfacing to roll just so on the collar. Out came all the pad stitching, the collar, the interfacing and turn the collar going the right way - some how I got confused and put it in backwards again (see, even we advanced students make mistakes), and had to take it all out over again.....grrrrrrr!
When I finally got it right, and the garment passed her inspection, she said to me, "Now, Claire, had that been me and I was doing this for a client, I wouldn't have spent all that time doing it again, I would have recut it as it would have been more cost effective!!!" Grrrrrrrr. I think I went bald for a couple of months while I pulled my hair out - we laughed of course, but I was exasperated.
Then why did she have me do it - to learn the lesson - sometimes you can't redo it, and guess what? I never made that mistake again.
So here's the deal. Most of the time you don't have to worry about this on garments like short skirts, blouses and other shorter-seamed garments. I have to on my long skirts and trains - they are a different animal. The weight of that much fabric, the weight of the seam all take a toll on the seam.
If you can get a clean seam without this technique - go for it! It's the clean seam you're after. If you can't get a clean seam, try this technique. I think it will work for you.
