Now draw an line orthogonal to the line 0-B at B, across the page nearly to the other edge, and measure off half the BUST measurement plus 5 cm (or 2"). Mark this point (C). The orthogonal line may be drawn using a square, but you may also measure the distance from the top of the sheet to the point B along the line OB, and slide this measurement along the top of the page to another point some distance from the first line, and mark a new point. Then align the ruler along the two points and draw across. <br><br> A word about precision here - the more precise your work, the better the fit in the final garment. Some round-off errors are inevitable, but you should try to be as accurate as possible, to 0.1 cm or than about half a 0.1" increment. The distances sound tiny, but you are only working on half the garment, so the actual errors are doubled, and in some cases multiplied even more. Also, errors tend to accumulate, rather than cancel themselves out, in this kind of process. If you make an error of 0.2 cm once, then a second error, then a third, you are now carrying more than a cm of error in the final garment. These errors accumulate quickly and will slew the results substantially.

    Is there any way that you can let me know which measurements added on are the ease measurements? 4 inches seems like an awful lot, especially for fitted shirts and t-shirts. I would be happier to half the ease suggested in this to make a closer, but still comfortable fit, so that I have a small sloper to start with that I can add more ease to later for jackets, coats, etc.

      The 5 cm addition over the half-bust measurement is for ease, yes, so 10 cm total ease. If this seems a lot, make it a little smaller, although this sloper is for a close-fitting bodice – the sloper for a loose fit bodice has considerably more ease than this (i.e. 14 cm!). I’m not sure of the logic behind so much ease – I’ve always just trusted these ideas and used them, mostly successfully. But you are welcome to experiment with them! The jacket blocks I use recommend 16 and 17 cm ease, so considerably more again.
