The cunning plan for the sails. Heming & stitching is difficult to get anywhere near to scale, unless the scale is large. So I experimented with the flying jib, worked very well. Except I have the bolt rope on the wrong side. I had tried this on glass before but the glue puddled showing badly.
Using the Paper pattern cut out the cloth ( I use ticking) With at least 1/2" all around. Mine was washed & ironed. This was because it has been folded in a drawer since the last boat.
Cut 4 Teflon blocks & drilled 2 holes ( Teflon cut from an old chopping board). A panel pin through holes one up one down. Place paper pattern on a board, nail the blocks so the nail sticking up is on the point. The other nail is clear of pattern, this will allow the block to pivot. Wind a string that has been soaked in PVA (water resistant type) around the nails.
The cloth is slightly dampened with a spray, not to much or it will be to heavy & also the glue could run. Push the nails up through the cloth letting it sag again not to much.
When dry remove it from board, cut off the excess cloth as tight as possible to the string. I then mark the panels with pencil. I do this on both sides, after the first side I tape it to the window so I can see & get them the same. Then give sail a coat of very watery coat of PVA, some mixed with acrylic paint.
Seen on my model Flying Foam I had over done it a bit.

First photo a hit & miss vent, cut to make gratings, painted streaky brown. This is not my idea, but its a good one.
The hawser hole finished & the stern ready for filler & paint. Will finish hull paint before completing topgallant rail.
Although I have a stand still using the pillow, as it makes a good pin cushion.
