Now, the bit I've been itching to get to, furling the sails
First I cut the sail (bit of a guess-timate since the one provided is moulded furled) and stitched to the yard arm. The corner is then pulled up to the yard and tacked to the yard.
Them the circled area is stitched to the same point as the first corner
And you get this, front view;
And rear
Next the middle part is stitched together, and then to the yard.
Last but not least, the reefing ropes, front
And rear
Then just a bit of wood glue to nip the edges together
