Welcome to the third part of the Mrs Darcy Wears the Trousers tutorial. Now that the front pieces are assembled, you are going to prepare the back pieces and attach them to the corresponding front pieces. Just you you did last week, please repeat each instruction for the other side of the trousers.
First of all, you need to insert the darts in piece 2. Make sure that you’ve accurately transferred your markings to your fabric. If you are new to darts, I strongly recommend marking them on the wrong side of the fabric as well, so that you can see the line that you are sewing along.
Working on just one dart at a time, fold the fabric right sides together so that the two diagonal dart lines lie on top of one another. The excess fabric should be on the wrong side of the fabric. The trick with darts is to iron them flat, pin them along the sewing line, and sew from the fat end towards the point. Here is my pinned dart. I’ve used a horizontal pin to mark the end of the dart.
Never sew all the way to the point (stop a few mm before you get there), or back stitch at the point; just leave your ends long and tie them in a granny knot. This prevents the point from puckering. You can see my finished dart, with long ends at the bottom, here.
When you’ve completed both darts, press them towards the centre back seam. Here are my completed darts.
It’s now time to attach piece 1 to piece 2 along the side seam. Lay out piece 2, right side up. Find which piece 1 goes with it by laying them on top, wrong side up. The correct piece is the one on which edge F is aligned with edge H, when they are placed right sides together like this. Pin and sew seam FH from the top to the bottom, so that the top is lined up perfectly even if the bottom isn’t. You will need to ensure that the pocket extension piece (piece 5) is straight. You can see my pinned pieces here.
Then press this seam open, as I’ve done in the photo below.
Now that each leg of the trousers is constructed, you’ll be working with the both legs at once as you sew them together.
Sew the legs together along the crutch seam. Arrange the trouser legs so that they are both still wrong sides out and right sides facing, with each piece 1 on top. Place them next to each other in an ‘A’ shape so that edges CK, which will be lying on top of each other in each leg, are facing each other at the top of the ‘A’. You can see mine laid out like this in the photo below.
Pin edge C of the left leg to edge C of the right leg. Starting from the top of the trousers, sew seam CC towards and ending at the end of the curve (the crotch point). In the photo below, you can see my pinning and I am pointing at the point that I am going to sew to. Do not sew on down the trouser leg.
Turn the trousers over, and repeat these steps for seam KK. Here is my pinned seam KK, and again, I am pointing at the point to which I am going to sew.
Press both seams open, taking care not the distort the curves.
Next, you’re going to sew the trouser inseams. Lay out your trousers, still wrong sides out, so that pieces 1 are on top again. They should look like this:
Align where all four parts of the trouser legs meet at the crotch, and pin. Pin seam DJ on one leg. In the photo below, you can see that I’ve pinned this seam on one leg. The scissors are pointing at the crotch point.
Sew from the crotch point towards edges E and I. It’s important that you sew both seams in this downwards direction. Repeat for seam DJ on the other leg. Press both seams open, as shown in the photo below.
Turn your trousers the right way out, and admire! They should look like trousers with a really big waistline. If you gather the top, they will look like mine do in the photo below.
That’s all for this week. Next week, you’ll be finishing the trousers by adding the waistband and fastenings, and finishing the bottom hems.
How are you getting on? Is this your first pair of trousers, or are you an old hand?
