Seams To Fit Part 3: More Power to Interlining!

Pinning seams becomes extra important when working on sewing narrow, curved, very fitted pieces together. I wanted a stitching line that runs precisely along the stitching line I created when fitting the test garment and creating the pattern. It went a bit against my casual, arty bent to be concerned with being as neat as a pin. It just wasn't a natural skill for me, and I had to think carefully about the process.

In my last "Seams To Fit" posting, I described how I used stitching marks on my interlining pieces to define the stitching lines on the fashion fabric it's backing. In both part 2 and part 3, I described how I made sure the fashion fabric was matched up properly.

Now that I was getting ready to sew each bodice piece together, I began to think of each piece as more of a section. That section is composed of one appropriately shaped piece of fashion fabric (the denim that shows on the outside of the bustier in my case) backed by an equivalently shaped interlining (a blue plaid cotton flannel). When it's prepped, one section is like one pattern piece.

At this point in the process, I needed a way to join the stitching lines of each section precisely to it's neighboring section. When working on doing the same operation on the inner fitting shell of the bustier (then I was joining the cutil/lining pieces together) I'd found this to be rather challenging. I was constantly turning the sections over and finding that the pins weren't going through into the stitching lines.

I marked the stitching lines all the way around each section
with pins, using the stitching lines marked on the interlining

I figured out the best way for me to get the sections joined together precisely, the second time around. In part 3, I describe how I'd marked each section (equivalent of one pattern piece) marked all the way around with pins. The pin heads show on the interlining side. Now, I could line up each section (one fashion fabric/interlining section for each pattern piece) with it's corresponding section. 

Working pins through from the stitching lines on one section
to find the stitching lines on the other side.
Here you can see a couple of pins I've already pinned through from the other side.
These are ever so slightly off!

When I laid, for example, piece 1a next to 1b, putting the fashion fabric (right sides) together, I now had pins on either seam line. I moved down the marked/pinned stitching lines pinning in the direction of the seam. As I moved, I worked another pin from one side of the stitching lines into the set on the other section. My fingers could feel that the pins were marrying up. I could, and did, still flip the sections back and forth, but it went a lot more easily than it had in the inner shell.

The only Photoshopping I did was to
change the fabric of my dress form, and
swap the real background for my little
gingham and scissors creation:-)

When I went to do the actual sewing, things just sewed up better. I only had to stop and unstitch a very short distance once. 

The proof is in the denim pudding. My bustier's outer shell is coming along and fitting snug and right.

The fitting shell that goes below will provide the support the garment needs to allow the garment to leave my dress form and head out into the world.

Figuring out techniques for sewing seams precisely is one of those thing that keeps me...

Seams To Fit Part 2: Making My Mark (Technicos)

Previously: Seams To Fit Part1: Little Less Laxity

Figuring out how to eliminate using a tracing wheel, has me making a stronger mark that is also less likely to damage my pattern or fabric.

How I'm Marking My Bustier Seams

• I do not include seam allowances on the pattern piece

• I watch the straight of grain (SOG) carefully.  SOG is an issue with the narrow curved pieces in this garment. I need to be sure that seam lines are drawn correctly, relative to the SOG.

•  I carefully mark the seam allowances in, around the pattern piece.  on one side of the double layer of fabric. I was originally using a toothed marking wheel to do this, but I realized there is a better way, for me, that creates a more visible mark on the other side.

On the top, right along the edge of my no-seam-allowance pattern, I make a dashed marking all the way around with a colored pencil. Underneath, I've placed Chacopy marking paper.

•  Then I draw on the seam allowances. I'm using a 1" seam allowance. I could use a double Clover wheel to get a precise 1" added on, but in fact if my seam line is just right I can be somewhat  general about a more-or-less 1" seam. Because I won't be positioning my needle relative to the cut edge, as I typically do.  I will be positioning my needle over the actual seam line.

Marking technique

- Can use Clover double wheel to mark at seam line and at desired width out. I have done several 1" seam allowances, and can mark those with Clover. Can also do them smaller
- Because my marking wheels are spoked type, they impact my pattern (when I have patterns with seam allowances) and they also can put holes in the fabric I may not want
- Marking seam lines with colored pencil and waxy Chacopy paper underneath gives me a stronger mark than running the wheel along the seam line. This also avoids fabric or tissue damage or holes.

Seams To Fit Part 1: A Little Less Laxity - Learning Precision

I'm improving a lot of sewing skills while working on my bustier project. For one thing I'm doing more pattern work, which is not only helping me to practice creating a physical pattern (I began with a commercial pattern and altered it - a lot). Also I'm learning to use the actual resulting pattern in new ways. 

I've changed my concept of when to create a seam allowances, at least for this very fitted garment. 

Creating a pattern with no seam allowance, is starting to be useful

Typically, when working with a woven fabric, I've used the standard 5/8" seam allowance that comes on a commercial pattern, or else added that same measurement to my own pattern. I knew that traditional patterns are often created with no seam allowances (Burda Magazine patterns are an example), but I didn't understand why that was done. Now I have a reason to leave that allowance off the pattern.

It has to do with fit.

I don't usually make fitted garments. If the seams I sew in, say, a loose shirt project aren't absolutely, precisely the same as the original pattern it's probably not a big deal. I sew the back to the front at more or less 5/8" away from the cut edge. A little extra or less between a couple of friends, and you're not going to notice the lack of precision in the finished project. 

 A bustier, however, is an ultra-fitted garment. In addition it covers much less body area than that loose shirt. Oh, and by the way, instead of that loose shirt's one back and one front piece - the back of my bustier is three pieces. The front is five pieces - several of which are extremly narrow. And those eight pattern pieces cover less surface area than the loose shirt's two.

If I'm at all casual about the seams whose positions I've carefully detailed while fitting this pattern, the garment is in danger of being too tight to fit. Or it may simply fall off!

I need to know, when I sew, that the seams I planned to sew during the fitting stage, are the ones I actually do sew. The first important thing I do to achieve that goal, is by marking my seams accurately. My goal is to get the seams within 1/8" of what I've decided is correct. I may still loose a little one way or another. My final back and front seams will make up any final corrections, but if it's very much off it will be noticeable. I want to avoid that.
