If you want summer weight, this is moderately close
Caccioppoli / CP350113
43% LANA, 32% SETA, 25% LINO
I found something similar to that from W. Bill, but was hoping for a brown/cream base...
Thank you all for the suggestions. I didn't think it would be so hard to find a comparable cloth, though. Akamine's Royal Line had a SC made in a similar fabric and it caught my eye a few years back and I saved the pic (4th from the right):
Still keeping my fingers crossed for finding what I want!
