+This pattern is probably good for a relatively wide range of dates: I've
+seen on the internet grainy scans of ads from the 1860 that seem to use
+a pattern like this one, and it should work up to the Edwardian era, but
+you will have to do some research on the appropriate shapes of the front
+opening and especially collar and cuffs for earch era.
+
+I believe that the original instructions assumed that this shirt would
+be hand sewn in the home, but by the 1880s sewing machines in the home
+were most definitely a thing.
+
+If you want to use a machine, your options are to sew by machine
+everywhere the instructions say to backstitch and handsew everything
+else, or to sew by machine the backstitched seams and topstitch every
+time the instructions say to hemstitch something; buttonholes should
+probably still be done by hand, however.

 Instructions

+Cutting
+^^^^^^^
+
+Cut the full rectangles for the front and back.
+
+.. figure:: gri_33125012088023-770.svg
+   :align: center
+
+If the fabric is non-directional and has no right and wrong side, the
+best way to cut it is as described on the book fold the rectangle in
+such a way that the sides will meet precisely in the center and bast
+them together, then fold them in such a way that the distance a – g and
+h – g is the desired width at the cuff, and cut all layers of fabric
+along the fold.
+
+.. figure:: sleeve_cutting_pattern.svg
+   :align: center
+
+After re-opening the fabric, you will get the shape in figure, and you
+will have to attach the small gusset to one side of the sleeve to
+complete the trapezium. Note that because of the sewing allowances this
+won't be a precise match, but the tolerance in this pattern is enough
+for it not to be a problem.
+
+Cut four of the shoulder pieces, two of the front bands, two of each
+collar piece and four of each cuff piece.
