More on the Marcy Tilton jacket

Since Marcy's Vogue 8430 pattern is meant to be used with boiled wool, the edges are supposed to be left raw, but that doesn't work as well with the thinner, lighter sweatshirt fleece that I used so I'm  trying to figure out what to do to finish the edges of my new white jacket. 

I was thinking I might go around the outside edges with a blanket stitch, using the same off-white thread I used to construct the rest of the jacket with, but think I'll just try that on the back hem to start with, in case it makes the jacket too stiff, because its current drapeability (if that is a word!) is a large part of what appeals to me about this top.

I also plan to add pin tucks to the back neck since that will hopefully made it less wide and also help it stand up as it would if made from a fabric like boiled wool, but don't think I want to add decorative stitches anywhere else since I kind of like its plainness, esp. since a plain white jacket would go with a lot of different things.
