Well, I guess I answered my own question. After spitting out all my thoughts about Blouson, I just kept knitting. I made it to the shoulder decreases and started decreasing. I'll save an EZ experiment for an EZ pattern. And at the rate that this project is going, perhaps I will start one sooner than later!
Isn't it funny that when starting a new pattern, there is a section of the brain that starts rewriting before you even really know what's going on? I don't know that my way would have been easier, just different. Maybe that is part of the attraction to knitting - I get to problem solve even when there really isn't a problem.
Better to do that with my knitting than with something else?
