I found a fascinating original sewing "hack" while perusing The American System of Dressmaking, published in 1909. The author's tip is to finish the waistbands of corset covers, drawers, and petticoats with beading lace, so that you can "attach" these garments together by threading ribbon through the lace!
"One clever way of combining garments is to mount the petticoat and the corset cover separately on belts of ribbon beading, and to thread the two together with one ribbon. Then it is easy to separate the garments for laundrying [sic]. Otherwise, the corset cover and petticoat may be sewn to the same belt, or finished separately. Other combinations are corset cover and knickerbockers, or drawers, and corset cover, petticoat, and knickerbockers."
Have you learned any interesting sewing tips from period magazines, manuals, letters, etc? If so, please share them in the comments below!
