The shirt is finished! I don't have a picture of it!
Well, it pretty much looks like the last photo in the previous post, except that it has a collar band on it.
Interestingly, since finishing I learned about a different method of doing cuff bands and collar bands that would drastically help with my problem of too much fabric to fit a collar stud through (though I think it won't be a problem with this shirt). Instead of fashioning the bands from fabric, reinforced with interlining, simply use a piece of stiff ribbon or tape, such as petersham or a starched grosgrain. It would certainly cut down on bulk.
It strikes me as odd that all of the cuffs fasten from the centre of the cuff instead of at the ends. Since the first set of buttonholes is for attaching it to the cuff band, that means that half the cuff comes back over the sleeve and the wrist. I don't know if that would even be comfortable. I may have to draft a cuff like this and try it out, just to see what it's like.
In any case, I'll make a collar or two as well, and will probably choose something from The Cutter's Practical Guide (189?) or from patterns from the Costumer's Manifesto.
