I finally completed "the shirt," view F from Simplicity 3751. Granted it took me practically all day today, but I learned a lot. Sewing another one of these or something similar will be a snap now that I've figured out the meaning of the instructions and how it pieces together.
I do regret not altering the pattern to make the top longer. Voluminous styles like this tend to stick out like a trapeze top on me because of my chest. On longer tops I can belt it to show that no, I'm not quite the size of a mini-van, but this shirt is just too short for me to do that. Darn.
