I have some useful info for you if you happen to be making pants (like, for the first time). While your gorgeous wool fabric may have give up the yin yang, your bemberg lining will not.
Do yourself a favour and use seam allowances that are .25 inch smaller on your lining (i.e. make the lining a smidge bigger than the fashion fabric). Then, when you try to put on the finished garment, you won't feel encased in a slightly too-snug lining.
What can I say? You live, you learn.
PS: I'm starting to realize that the sign of an expert seamstress is one who can intuit how much fabric ease is required when transitioning from muslin to wearable item.
