I'm hoping both tees will work well in our temperate fall and winter climate, in the San Francisco Bay Area - if we ever get any cooler weather that is! Right now the weather gods seem to think it's still summer - actually a warmer summer than we usually get.
So far I've traced and dated the master pattern (view C) on drafting paper, leaving in more than enough seam allowances for altering. I'll probably use some commercial tee shirts for muslin/patter testing. I hope that, even though this is a knit, I can still get some idea with the help of my dress form Conchita, as to where shoulder and side seams need to go.
I believe that Marcy Tilton Thomas' sister Katherine Tilton, designed this pattern. Here's a newsletter where Marcy talks a little about the pattern http://www.marcytilton.com/index.php?cid=1050
