I used to do quite a few bottle ships as a kid. But I'd use rubber thread instead of real sewing thread so I wouldn't have to construct the ship to accommodate the complex rigging necessary to pull up the masts and sails. The rubber thread would do the job by itself once the ship was in the bottle.
That was good fun then, but it goes without saying that these ships weren't made to last... So I have always wanted to do a bottle ship by the book. – Well, here it is, documented and all. Have fun.
