Well I finished the Codpiece!
It is not quite what I was going for, but as you already know from my last post I LIKE IT!
Ok so I toke the lining (see last post) and I attached the silk after I had gathered it to the right length to the "swollen" part of the codpiece.
The outer part was made slashed and the slashing turned and sewn down, then the separate parts (the same as the lining) where sewn together. All this was then turned and pulled over the Lining with the Silk attached and then blind stitched closed.
