Building sleeves

The sleeve lining, with dags sewn on. Dags are backed in more green linen.

Outer 'puff' added at half-sleeve point. Box pleated for less bulk. Machine sewn down - velveteen band will cover the rough edges and the join.

Scary monster sleeve mouth! Argh!

Inside the outer 'puff'. Iron-on interfacing or moderate stiffness, and 'horse-hair' braid made of the purest plastic. Tacked very gingerly into place as there's nothing to hide the stitches on the outside.
The whole thing is looking rather spiffing, I must say. At this point I've got the panes cut out, and some are sewn and pressed, and the upper pleats are sewn in at the sleevehead. I'm a little worried at how careful I will have to be, sewing the whole sleeve to the bodice and keeping the pleats flat and pretty. And must remember to put the rest of the boning in BEFORE sewing the sleeves on!
This whole adventure took me most of today. And it's not over yet. Phew!
