I press seams too. Hems are usually blind-hemmer with modern garments, handsewn with historical reproductions. I haven't done the grain thingy with pulling the thread. I should try that next time I use a fabric that won't tear. I do always press the paper pattern pieces. I just can't stand wrinkly pattern pieces. I also do the layout the way the pattern says! Unless I'm trying to get the pattern pieces out of less fabric than it calls for. I wouldn't baste together a whole dress. I'd make a toile out of muslin, leaving off the sleeves. And I have hubby mark my hems for me. He's an engineer and a carpenter, so is very exacting in the marking.
Although the article is more of an advertisement, I really enjoyed the vintage charm of it. I know it doesn't reflect reality even for then, but wouldn't it be nice to have an entire uninterrupted weekend to sew?!
