I have no suggestions for you ..... I'm kind of old fashioned and like to purchase things IRL, where I can touchy-feely it and know for sure what I have.
I'm just a tad east of you, and find I have an abundance of quilt stores to visit, if I'm on a mission to find something specific. And a lot of them will be just as close to you or closer, as they are to me. Unfortunately, I don't know who has what types of fabrics, as I haven't been a big follower of fabric lines in the past and am starting to be more tuned in, in that regard now.
When I was on the summer "Yours to Discover" shop hop, the shops in Mt. Brydges and Sarnia were/had done the Civil War Quilt and FWS. They had respected each other and not duplicated, but I forget which shop for which quilt. So I'm thinking one/both might have the CW fabrics you have mentioned.
