Take the cup, choose the right place on the cradle.
Pin the cup
See here how cup seams must match the notches on the cradle. We will be pining the cradle to the cup in critical points. Will be doing that to fix the cup position. Later we’ll pin all around.
The most important point is the one at the bottom of the cup. We will start from there. Grab the cup and the cradle altogether.
You have to arrange the cradle’s notch on top of your cup seam. Pin beside the notch.
Now cover the cup gently with the cradle to the side direction. You should have a notch to match a cup seam there as well.
This time pin directly on the notch and two more pins beside the previous one.
And the last side is the one that goes to the center. Hold both pieces and try to cover the cup. There should be a fabric that goes beyond the cup end. It should be 8 mm – our seam allowance! If you’ve used a different amount, that amount is what you should get. Place a pin there too.
Here’s one cup pinned in critical points (bottom, center front, side).
Ok, now pin all around to fix the cradle completely.
Baste the cup
And this is not ready yet. If you’re an advanced seamstress you can jump to your sewing machine. However, I do recommend for all of you to hand baste. I do it all the time!
And take the pins off. It’s a lot easier to sew on a sewing machine when you don’t have to worry about the needle stepping on a pin.
We did all these in one cup. It’s time to repeat the exact same steps for the second cup.
If you have cut and sewn the bra pieces following all instructions and notches they should be at the same level. Otherwise, you must find where the problem is. Find the cup you’ve attached wrongly to the cradle, unpick the baste and try sewing it again. There may be other problems, more severe: cradle was cut wrong, the cup was cut wrong, the cup was sewn incorrectly.
And one more check. Take the bridge and try overlapping cup edges. The distance (marked with a red segment) should be equal for both cups. If it’s not, then it’s once again all possible mistakes I’ve just stated above.
One thing is clear at this point. Any mistake would surface here. Actually, one mistake may be the poor pattern design and not your fault This is why we did all the pinning and hand-basting by the book. OK, ready for sewing on your machine.
Joining the cup to the band
Use a straight stitch. Cup is facing the needle.
Sew both cups. One at a time, of course. And this is what you should have.
The stitch should intersect not one incision on the cradle. It should be like 2 – 5 mm away from the end of each cut. Re-stitch again, this time a little far from the edge, if it’s not ok.
Take the baste seam off.
And the hard part is gone! This is starting to look like a bra.
