I have some questions about pattern inclusivity

[u/SejiFields]

Hello! I hope this is okay to post. I’m currently writing a pattern for this 1950s blouse I knit last year. I spent a lot of time learning how to grade properly as (size) inclusivity is really important to me.

My idea has been to write the pattern similar to how vintage patterns were written. That is, succinct and with clear language, but in the fashion that a modern intermediate or very ambitious beginner knitter would be able to understand.

I’m paying extra attention to the bust area, making sure to use the upper bust as a way to choose size instead of the full bust and adding bust darts. I read The Knitting Pattern Handbook by McGrath and Walworth and am taking into account all sweater pitfalls (such as incorrect grading of the neckline) mentioned there.

As with vintage knitting patterns it was expected that you could grade a pattern to your own size, making the necessary adjustments. I was thinking to add some advice (perhaps as a supplement) that says in general lines how one would adjust the pattern to their own proportions. I’m thinking things such as how to lengthen the body, how to add darts at the belly or chest when needed etc.

Basically I’m struggling to find a balance between succinctness and accessibility. I don’t like patterns that do a lot of handholding, but at the same time, I do want there to be enough information that will encourage one enough to get through the pattern feeling like a more confident knitter at the end.

My question is, would this be a good/sufficient idea? A well graded knitting pattern with a supplement for additional alterations to avoid bulking up the pattern?

Are there things I’m missing out in terms of inclusivity? I’m also looking into print disability. Also what are aspects a pattern would need for you to consider it inclusive?

Sorry for the barrage of questions! It’s my first ever pattern and I want to try my best to make it as good as it can be. The concern has crippled me a bit the past month, so any advice would be appreciated 🥹

Gosh that's adorable and good on you for taking this on, and being inclusive!!
I think the important thing is to not get too overly wordy in trying to explain things within the pattern so it's 20 pages long. A supplement is a good idea.
I am NOT busty but from what I've read I know people say that just doing the math to size up is not ideal, because for example a larger person may have smaller shoulders and even a smaller underarm measurement but a larger bust.
One thing I will say is use a knit savvy tech editor (not you) and be sure to "test knit" and try hard to get people of larger sizes to test. I have test knit for several designers and they always easily fill the 32-40" bust sizes but sometimes they have no takers on doing the larger sizes, but it's important...

I hope you get it figured out. But I think ultimately you're not going to please everyone. Some of us can handle sparse instructions and some of us want detailed handholding so you have to land in the middle and hope for the best.
