OMG indeed. Is the silk in your stock a color you can/will choose as a replacement? If your new vest is to be used in colder weather more often, go with your last choice of linen lining. I wouldn't want overall stiffness (until broken in properly) make the vest uncomfortable.

Please don't let my questions or suggestions stop you from going forward. As a "cheap seat observer" I don't mean to distract from your success.
