I’m so sorry that you’re experiencing so many problems. I’ll see if I can do the tutorial over the coming weekend. More snow is forecast, so I’m guessing I’ll be house-bound, again.
The methods of drafting by hand are pretty much the same as drafting on Seamly, except that you use the tools instead of different types of rulers and pencils. I suggest that you draw a few points and lines on a new pattern file and use each tool in all of the toolboxes so that you have a ‘working’ idea of how to use each tool. Here is a PDF that @Pneumarian created last year on how to use the tools:
Seamly Manual.pdf (211.4 KB)
Then you may head over to my blog & do the (very old - 2020, so somethings have changed since then) tutorial that I did using the Burgo method. It’s the woman’s basic bodice, but it may teach you a bit and there are accompanying videos on Youtube, that deliberately have no sound.
There’s also a very nice introductory PDF that @peterh wrote, only last year, that you can download here.
I hope some of these can help you.
Edit: I just remembered that I did a bit of a tutorial on the Mirror tool in this topic that may also help you.
