Ysolda Teague's Ishbel was a fun knit. I used a skein of Araucania Ranco Multy (that's how they spell it) and followed the directions for the small for the stockinette portion and the large for the lace portion. I had a spare skein on standby, but ended up not needing it at all.
(Apologies, I did not notice the bra strap until later.)
