See this link, we're trying to do a GMTO on this fabric.
There's a H&S Crispaire in forrest green (3). I have no experience with the cloth and have read on here that it is more refined than fresco - possibly not suitable as an odd jacket. But it may be an alternative rather than trying to put together a run of fresco.

I've been looking for something of that color, and I'm going to order the racing green new fine worsted from dugdale and see. Planning to make a blazer suit out of it, hope it'll be good for it.
