Interfaced on the inside

Today I start making my burgundy pinstripe Tennant Suit jacket. Now I KNOW it’s not a screen accurate colour - don’t write in! - I’m only doing it as a dry run before cutting into a single inch of my blue fabric.

I have dyed the blue fabric to the right colour, so have dyed some red pinstriped fabric (from the same source as the blue) to a burgundy so I am comparing like-for-like material (see below).

Having started (but not finished) a similar jacket earlier in the year, and a Calico Test only a couple of weeks ago, making it up should be relatively easy and quick.


Before I can do any cutting I need to stiffen the fabric. It is, in reality, a shirting fabric, so quite a lightweight cotton. I did initally wonder if I had found the right material, but a friend pointed out that there was a publicity still where you could see the inside of the trouser ankle - and it was white, which had puzzled him (see below). This made perfect sense to me - it had been interfaced! What I needed to work out was how stiff I needed to make it.

In the UK we have a main manufacteurer for interfacing, Vilene. Their basic range is a Light-weight, a Medium-weight and a Heavy-weight version. This determines the thickness. Each then comes in either a Standard or Ultrasoft option. This controls it’s flexibility.

Since the fronts of jackets are usually interfaced, I am going for a Medium Stanard for the body, but I want the sleeves to be more supple, so I will use a Medium Ultrasoft for the arms.

Usually you would cut the fabric then cut matching shaped interfacing and press them together. But since I need to interface everything I am going to press it first, then cut the pre-interfaced pieces after.

Annoyingly the fabric and the interfacing come in different widths, so I do a strip of the fabric and save the off-cut for later.
These off-cuts, once interfaced with the Ultrasoft, will be fine for the sleeves, so nothings really going to waste.

I start by cutting the fronts, making sure I line the edge with the pinstripes just like the real suit. (see right).

I then cut the side underarm panels and all the smaller fiddley bits relating to the pockets.

I need to do a bit more work on the pattern for the back, so will cut that a bit later.

Finally, after interfacing the off-cut part of the fabric with the Medium Ultrasoft, I cut the arms of the jacket.

This now gives me enough to begin work assembling the jacket, but I'll save starting that for another day. . .

  2. So Iʻm thinking since burgundy converse go with the blue suit, you shall be wearing blue converse at some point with this if it all turns out okay? ;)
