I did swatch up a square with a size 8 needle, and I liked the drape of it, but then the stitches become inconsistent looking. I think that would come out in blocking, but anyways I decided to stick with my original idea on size 6 needles. I find it's usually in my best interest to stick with the original vision I have for a project. Once I rethink it too many times the vision is lost.
I did have to shorten the sleeves and I think I like it better this way! I'll try wearing it a few times and see what I think. I can always attempt to order a couple more balls of yarn.
Here's a shot before blocking. Just have to weave in those pesky ends and cinch up the collar at the back of the neck, which I will leave for after blocking.
