For a long time I've wanted to try the technique described in the article The Bridge Engineer - The Keyhole on the Bra making blog (unfortunately no recent entries any more).
In the past week I tried it, and this is the result, it's not exactly what is described, I gave my own twist.
Important is that you can only do this on a partial band bra. I've used my own pattern and converted that to a partial band bra. I'll write a post on how I did that later.
Instead of paper as described in the article, I used a piece of washaway stabilizer.
A picture to illustrate this.
The idea is that you can change the shape of the center front tab as you like and use paper (or washaway stabilizer) to help you to keep everything in place while constructing the bra.
It's made of a few pieces left of a lingerie set I made two years ago, this is a very wearable muslin. However, it's not completely what I wanted. I made a change to the upper cup, to try to make a more horizontal line, instead of the diagonal from center front to shoulder strap. Must try again with a lace that has less stretch, that might make a difference.
Searching for the right change, as I have a RTW bra in mind that I want to copy.
