I’ve spent a few years working on self drafting sewing patterns, but after going through pregnancy and postpartum my block (which was not perfect before) was just clearly out of whack and needed a redo. I started using the instructions in Helen Joseph Armstrong’s excellent textbook Patternmaking For Fashion Design but I was pretty frustrated at the bust limitations. Many ready to wear clothes and sewing patterns are drafted for a B or C cup and follow a bit of an esoteric “perfect” ideal figure, and this just doesn’t jive with my shape.
I found dresspatternmaking.com during a fit of frustrated googling and was really enamored with the method that focused on fitting the bust correctly as part of the drafting rather than drafting and then doing a full bust adjustment. My mother and I got together and had a great learning experience taking measurements on each other and then returning to our respective studios to make mock ups. This was back in.. oh.. January (2025) I suppose, perhaps February, and I’m now on version seven of my mock ups (!!).
For me a fundamental issue I have always had was with armscye (armhole) fit, particularly this feeling of constriction and cutting in when I’d have my arms forward. I initially attributed this to incorrectly drafted armscye but after some sleuthing and help from the internet, it turned out to be a back ease issue. Once I had that epiphany things fell into place pretty quickly and I think/hope it will only take a few more mockups to finalize the block.
Here’s a photo of version 7 of the bodice back

The primary change in this version was to remove excess ease that was occurring in the lower back but without removing ease from the waist. I followed similar instructions to what you’ll see for doing a narrow back adjustment but applied it to the lower back instead. It was tricky to remove ease without totally distorting the side seam, and I’ve had to compromise a bit and err on the side of leaving a bit ease in.
I’m looking forward to the next mock-up to test the fit.
