The finished, blocked and woven-in article.
This first photo shows the detail better...
while the colour is better in this one.
The pattern is Cobblestone by Jared Flood, published in Interweave Knits.
The yarn is New Lanark 100% wool aran in the colourway 'denim'.
I used 2 long 4.5mm circular needles throughout.
I made no modifications to the pattern as written!
I knitted the smallest size, but with my gauge and the fact that this yarn really relaxes when blocked, it came out at approximately 42" chest with 2-3" positive ease.
It fits the resident radiologist perfectly and he's even mentioned the possibility of wearing it to work so he must like it!
