Hey there! Hila, here are the tips from the vintage booklet “Tailoring” published 1945 by The Spool Cotton Company.
I’ve never seen instructions like the ones given here. I think these are more labor intensive since the interlining is considered a separate layer from the fashion fabric. “Reader’s Digest Complete Guide to Sewing” has a simpler process: the interlining and fashion fabric are basted together and then cut and treated as one layer. The only thing these instructions have in common is that the back interlining piece will not have the pleat the way the lining does and has the back seam abutted. This is how I learned to do it and it works very well.
Still, it’s very educational to see how clothing was constructed in the past. It helps understand how techniques are always evolving.
