My Tailored Blazer Project Continues: Preparing the fabric and interfacing(s)

If like me, you’ve ever dreamed of having that perfectly tailored bespoke suit made precisely for your own body, you’ve probably wondered where you might procure one. Earlier this month, the BBC featured a young London entrepreneur and tailor named Daisy Knatchbull who has opened the very first all-female tailor shop on the storied Saville Row in London. You probably know that Saville Row has, up until now, been exclusively focused on men’s tailoring. But not any longer. The story transported me…

But, did you notice how much such a suit will set you back? Enter an opportunity for all of us who sew. We can create these bespoke suits for ourselves at a fraction of the cost – but a lot of sweat equity it has to be said! And that’s what this project I’m in the middle of is all about. I’m doing my own self-guided course on tailoring.

In the last post, I created and altered the muslin. By the time I was finished with that, I had a well-fitting pattern (I hope) and was ready to finally get that fabric out and begin to cut.

You might remember that the fabric I’ve chosen for this project is a silk and cotton tweed and to say that it frays would be a serious understatement. This is important to know if (a) I want the seam allowances to be accurate, and (b) I want to maintain my sanity. So, as I begin to lay out and cut the fabric, I have to keep this in mind. First, I try not to handle it too much and second, later on, I’ll actually take the time to run a machine stitching line down all important edges. It’s worth the time. But back to the cutting out.

There are a lot of moving pieces in a tailored jacket that has welted flap pockets, side panels and two-piece sleeves. And since this Vogue 9099 pattern is a Claire Schaeffer couture teaching one, it has numerous pieces.

Instead of having to create your own lining and interfacing pattern pieces, they have been provided, so I must separate out the ones that are just for the fabric, the ones that are cut from fabric and interfacing, and the ones (actually there is only one) that are both a fabric and lining pattern. I’ll deal with the lining later – I can only cope with so much fraying fabric at one time. The lining is silk charmeuse and I’m well aware of that baby’s tendency to fray into super-thin silk filaments. Later.

This isn’t the most expensive fabric I’ve ever used (that would have been Italian cotton for a shirt for my husband), but it wasn’t cheap, either. So, I take a moment to ensure that I’m relaxed and calm before I attack it with the shears.

So many pieces!

Once I have that done, I need to cut the interfacing pieces because there will be no sewing of this project until the interior body and collar shaping are done.

I’ve never worked with hair canvas before, but since this one is fairly thin, it’s easy to work with and thankfully does not fray! I’ve chosen this light-weight canvas so that I don’t change the character of the fabric too much. I want shaping, but I want soft shaping.

According to the pattern instructions, there are a few pieces of interfacing that need to be cut from “batiste.” I thought I knew enough about fabrics to know what batiste is, but this didn’t make a whole of sense to me especially when I noted that the batiste was to be used to interface the undercollar and pocket flaps.

So, I go to my favourite textile bible and find out that I am right: batiste is lawn. In fact, “lawn” is called batiste when it is made from cotton and called “handkerchief linen” when made from flax. Bottom line: it’s very thin, and not at all what I would have thought ought to be interfacing for an undercollar – but it might be right for pocket flaps. Nevertheless, I decide that the decision of what to put where could come later. I follow the instructions and cut it out. However, I don’t have batiste lying around, but I do have silk organza which has many of the same characteristics of batiste (sheer and lightweight and able to hold its shape being chief among them), so I decide that silk organza would be an even better alternative. We’ll see.

With the pieces all cut out, it’s time to mark everything – carefully. One thing I do know about making jackets – traditionally-tailored or Chanel-style – the marking needs to be accurate and plentiful.

My favourite kind of marking for tweed uses Japanese cotton basting thread for lines and tailor’s tacks. Remember what I said about fraying? I could have handled this by using couture methods – cutting the seam allowances off the pattern, laying everything out in a single layer, rough-cutting at an inch or more and finally thread-tracing the seam lines. I choose not to do this. I cut the pieces with the regular seam allowance then carefully measure my way around the periphery of every piece adding thread-traced seam allowances. This should keep me on the right track when I get to the side seams which are the most important ones for fitting this jacket for me.

Of course, I have to figure out how to thread-trace the pieces that are cut in a double layer without removing and replacing tissue pattern pieces multiple times. I decide to use the technique demonstrated in the video below for the first step, but I really hate all those tails. That’s why I then do running stitch lines connecting the tails and remove all the annoying little bits of thread. (No, I didn’t do that on the seam lines on the periphery – I measured them all as I did my running stitch. See my little green sewing gauge above.)

It is after this step that I decide to machine stitch around all-important seam allowances (which will give me the right fit in the end) to reduce fraying. It is my sanity saver.

Marking the interfacing is also important and is much easier. I use tracing paper and will use one of those pens whose markings disappear with heat and steam. (I’ve just acquired a couple and am tickled at how well they work – unless, of course, you inadvertently steam away your markings before you need them as I have done several times).

Now that it’s all cut out (except for the lining) it’s time to learn as much as I can about things like “pad-stitching” and other aspects of what goes into the shaping of the interior of the jacket. I’ve started practicing…

What I’m learning is that there are as many “best practices” as there are experts in the field of tailoring. I’m going to try to figure out whose method works best for which aspects of the project – I’m not planning on following the pattern instructions to the letter (sorry Claire Schaeffer!).

I’ll share that with you next.

Cutting out & marking my ‘Little French Jacket’ for a perfect fit

-Luxury must be comfortable, otherwise it is not luxury.-The more expensive the fabric, I buy, the more trepidation I feel just at that moment when, shears in hand, I hover above the swath of fabric on the table in front of me. I have already prepared the tweed bouclé by steaming it within an inch of its life, and I have carefully laid it out, in a single layer to ensure accuracy. I have carefully measured the grain lines and pinned them precisely where they are supposed to be. But this time around – on this third Little French Jacket – I’m using a slightly different approach to cutting. Rather than simply following a seam allowance, I’m just doing a rough cut. I’ll be marking seam lines and using those for a more accurate fit. And yet, here I sit, shears at the ready, taking a moment to pause and breathe before that first snip. Once that’s underway, I’m committed. Here I go.

This is actually fun, I think as I snip away ensuring a minimum of an inch (which I am eyeballing), all around the perimeter of the muslin pattern that I have already fitted and prepared. Once I have all of the pieces cut out, I am ready to thread trace all of the important markings.

I’m using a product that is new to me. When I viewed Susan Khalje’s couture dress class (I am working on the dress too, but that’s a whole different story!), she introduced me to the concept of Japanese cotton basting thread. She sang its praises so much that I had to have it. I also had to have her large sheets of waxed tracing paper that I used to mark the muslin pieces, so I ordered them all together.


It’s interesting stuff. I have these skeins in four different pastel shades and have selected the pink for my thread tracing. The instructions are to tie a ligature around the skein and cut it in one place. Then I am to take individual threads that will evidently come straight out, not disturbing the remaining thread. And it will be in the perfect length for basting they say. Well, it actually works. So I begin.

First I trace all of the seam lines. At the corner of each intersecting line, I use Clair Schaeffer’s method for taking the corner, knowing that I’ll be able to snip those corner threads to remove them in due course. And I know that I have a precise corner point.


I also use thread markings for the notches, circles, quilting lines on the front (as I mentioned earlier when I examined the pattern, I’ll make up my own mind about where to put the back quilting lines when I get there).

I have cut this out in one layer, but since I made up only a one-sided muslin pattern (that may not have been the best idea I’ve ever had), I do my marking and thread tracing as I go. In other words, I cut out one centre front piece, mark it and then take the muslin pattern piece off and cut out another one and so on. I have been very carefully marking the wrong side of the fabric with a piece of patterned tape held securely with a safety pin. The fabric is essentially the same on both sides, but it would be awful to find I’ve prepared two right front sides rather than a front and a left because I mixed up the right and wrong sides!

fringeIt’s important at this juncture to say that I am also being careful not to cut through any of the selvages. I am preserving them because they are fringed. I don’t know yet how I’ll trim this jacket — that’s a design decision for later. But I do know that I might want this fringe at a later date.

When all that marking is done, I move on to cutting out and marking the lining.

I love silk charmeuse against the body – but I’m not as big a fan of it on the cutting table. Usually, one would cut this in a single layer, but I am finding that using muslin as a pattern rather than any kind of paper pattern makes cutting this out double-layered so much easier. So that’s what I do. Again, I’m rough cutting because I’ll mark the stitching lines to use. I am using white waxed tracing paper and the same method I used with the muslin to mark the wrong side of the charmeuse.

I also need to cut out a piece of interfacing – it’s really underlining in my view, though, regardless of what it’s called on the pattern – for the front of the jacket to support the buttons and buttonholes. In my previous jackets, there was no such layer since they had open fronts.

I test a few fabrics and realize that the only option that will give me the look and feel I want is, indeed, the silk organza – only pure silk will do.

And so, now I’m ready to test stitches, cut out little pieces of iron-on interfacing to place behind the buttonholes, and start sewing. A jacket is on the horizon!
