I don't know the artist of this particular pattern but it is a good indicator of how the layout of my tunic looked. I didn't use a faced neckline because the wool was quite bulky, but the rest of the layout is very similar. I measured the wearer's body and added a little extra for ease of movement plus seam allowances.
The rest of the neckline was turned down with a small hand-sewn hem to reduce bulk.
I left this tunic plain so that the recipient could sew trim on if he wanted. I have yet to get a photo of him wearing it, but it looks nice on.
