*checks gussets of sailor's shirt*

Looks like I did two seams enclosed - off-set then folded under - and somehow finished the other two as though doing the double-seam effect you find on jeans. I don't recall having that much trouble with them. (Not like the current issue I'm having with the fall lining of my trousers. Need to re-cut those and totally redo them, which is going to be a pain.)
