Much to cover today so let's get to it. The best way to create a button fly is to look at a pair of RTW jeans and recreate one.
The button fly is essentially an additional fly shield sewn atop the left front fly extension. From now on I will refer to this as the left fly buttonhole shield.
Remember these? They are our right and left fly extensions as viewed from the wrong side (inside) of the pants. (The left fly extension edge is serged; the right side will be stitched and then serged to the right fly shield.) They are folded back at the center of your pants fronts, which you traced off your pattern piece -- or should have.
If you're unsure how I got to this point, please refer to your instructions or review last week's fly post. Everything is the same up until the zipper installation.
I made the left fly buttonhole shield using the zipper shield pattern piece from Kwik Sew 3504, but instead of cutting it with the curved side on the fold, I did the opposite.
We want the straight edge to be a simple fold. The side that's curved at the bottom will be serged (or overcast) and will face away from the fly.
I reinforced (or interfaced) the left fly buttonhole shield with an additional fly-shaped piece (not cut on the fold) cut perpendicular to the selvage to prevent stretching (width-wise). With this extra fly-shaped piece inside, I then serged the curved edge. So we're talking THREE layers of denim, two parallel to the selvage and one perpendicular. If my denim hadn't had stretch, two layers might have been sufficient.
We want to prevent this from ever happening:
Next, I measured my left fly buttonhole shield against my RTW button fly and marked where the buttonholes should go. Then with my Singer buttonholer attachment I made three holes.
I reinforced the holes with Fray Check, cut them open, and then stitched the left fly buttonhole shield to the left fly extension (and not through the front of the pants) along the outer curved edge. You need to make sure the left fly buttonhole shield does not stick out beyond the front edge of the fly. Remember how the front left fly edge is topstitched? Keep the straight (outer) edge of the shield inside that topstitching line.
From the inside it now looks like this:
I staystitched the top. From the outside it looks like this:
I now topstitched the left front fly (through all left layers), exactly as I did when I made my zipper fly (see Kwik Sew instructions for details). Make sure that when you're topstitching, you're clear of the buttonholes themselves. You can make a single row or double row of topstitching, as you prefer (Most RTW jeans have a double row).
Now let's address the right fly.
You're going to attach the right zipper shield just the way you would have if you'd sewn in a zipper, trimming the edge of the right fly extension (the piece that's part of the right front pants and folded back) at slightly less than half, and attaching the right fly shield, which you've created exactly the way you did for the zipper fly.
Recall that, with the right fly shield, the curved edge is the one cut on the fold, and the straight edge is raw (and will be serged) -- exactly the opposite of the left fly buttonhole shield.
I stitched and serged the right fly shield to the trimmed edge of the right fly extension. I then topstitched this along the vertical front edge from the front, exactly as I would if I'd attached a zipper. (Instead of a zipper, you'll be attaching jeans buttons.) Refer to the Kwik Sew instructions if you're unsure of how to do this.
From the inside, the right front fly extension should extend to the edge of the left fly buttonhole shield. Mine does not quite reach -- next time I'll make my left fly buttonhole shield a little narrower. I may still trim that extra width. (With white denim these details can be visible from the outside; not the case with dark denim.)
Even with RTW jeans, there's often extra width on the left fly buttonhole shield.
Lining up left fly buttonhole shield and right fly extension, I marked with pencil where I needed my small jeans buttons to go and attached them.
Here's how the fly looks buttoned:
And from the inside.
Finally, you'll want to stitch the bottoms of the two shield together and bartack through all layers.
The pant are almost done -- just need to stitch up the sides and add a waistband. He likes them!
Oh -- I haven't even mentioned my new sewing machine yet! More about that tomorrow (short story: $20 on Craigslist) but here's a peek.
LOVE!
