I've been working on a hooded vest with a deep V-neck and a kangaroo pocket. It has bobble trim around the hem, the pocket edges, the neck fronts and the hood. Since it's worked from the bottom up, the bobbles around the hem are worked on the first round. I'll be honest-- that round takes FOREVER-- but after that the knitting goes much faster, especially since I decided to use a chunky weight yarn.
I did realize early on that the bobbles along the pocket, neck and hood edges would be worked from the opposite direction-- that is, on the last row before binding off. I even did a swatch and it seemed like that would probably work. At least I thought it was worth a try, since I generally much prefer knitting on edgings to knitting them separately and sewing them on.
But as you can see from the above photos, the bobbles along the bound off edges (vertical) don't lie the same way as the ones along the cast on edge (horizontal); they want to flip back on top of the ribbing. And I really don't like the way they look when the edge is folded over (as it will be when the vest is worn with the hood down). The ribbing is also too stretched out; I prefer it more relaxed, as it is along the hem.
Plan B: Knit the edging separately, bobbles first, and sew it on!
