I found this project really easy. Time consuming, but easy. I followed the project tips from Kittson http://www.ravelry.com/projects/kittson/gwen-stacy

I stopped after repeating 1/2 of the extra length but wish I had completed it all. It’s not as slouchy as I’d like, but still fits well.

For the bobbles, I knit a stitch from the left side of the bobble along with the stitch after the bobble so I wouldn’t get a hole. In the row after making the bobble, I knit a lot of the stitches just before-on the bobble-and just after through the back loop to make it tighter.
