Glad to see even more DA cosplayers, woo!
I'm partial to the idea that Anders is rocking feathers, but both can achieve really nice looks.
^ As mentioned above, sewing feathers individually is the best way to attach them (most annoying thing about feathers is that they most often need to be clipped). By having control over the direction of each feather, you can layer and shape them to make a really flattering looking piece. The positive about fur is that you can obviously machine stitch it if need be. If you go this route (and I've learned this the hard way in the past from other costumes), cut the fur with a sharp xacto knife instead of scissors, or you'll get fur everywhere. If you need to sew it, you can "pick" the fur caught in the seam allowance out to make the seam pretty much invisible.
Please post your progress if you get a chance/finished product, I love seeing other people's work!
