Butterick Pattern Company, The New Dressmaker (1921)
“ Both the outside and lining portions are cut exactly alike, the seams stitched and pressed open. The sack and lining are then basted together, with seams turned toward the inside. The sleeve portions are gathered separately at the top. Sew the outside material of the sleeve in at the armhole. Turn the raw edge of the sleeve lining under, gather it and hem to the armhole. A tiny turnover collar may be added with the same kind of finish. The edges of the sack may be turned in and secured with a row of feather-stitching, or they may be buttonholed together by a scalloped edge. ”
