- wide scoop or v neckline won't fall off the edge of the shoulder
- Watteau pleats won't pull the neckline down at the back of the neck
- faced waistbands won't stretch
- armholes won't gape at the bust level
In the photos I am using the wider one which I think makes it easier to see.
Now I apologise but I am left handed, all you North paws out there will have to think backwards!
Step 3: Keep doing this every 1.5" or so, easing the seam onto the tauter tape. It's hard to tell but the seam and dress are curving inward quite nicely even now.
Step 4: Now using a double thread and smallish stitches, start to stitch the tape to the seam allowance hard up against the top edge, ensuring that the bodice seam stays fairly flat.
The is the section sewn in, and the next section also.
See how the bodice now curves almost as if it is molded onto cups. It's just taping that does it.
Nice curved bustline
You can tape without so much easing if you're just using the tape to stop a seam from stretching. Tape sewn onto the seam allowance (no easing required) of a puffed sleeve helps it to sit up, or sewn on the underside, to sit out.
It's one of those techniques that, once you get the hang of it, is useful for a range of finishing fixes.
For a watteau back, tape the whole neck edge, from waist at front right around to waist left. This reinforces the seam and helps it to bear the weight of the back without stretching.
No gaping on this bodice! :)
