You are in luck. I just checked my stash and it just so happens that I have 3.5 skeins of Pure Alpaca in Oxblood. just to make sure, the color is 2124. I looked on the website and it seems as though that's the Oxblood.
I don't mind selling, but will also consider a trade. Maybe PM me and let me know. Hopefully 3.5 balls is enough for you to finish your shawl.
