Dan's tip is a good one-- moose mane can be a bit brittle if it's dried out.
Wrapping both the dark and white hairs makes a nice segmented body on smaller hooks-- it's thinner than using the fatter stripped hackle quills, and although not an exact match, it gives a look similar to stripped peacock quill.
Over wrapping with extra fine wire or coating the thread underbody layer with head cement before wrapping the hairs helps to make it more durable.
I usually wrap several hairs at a time that are spread out in a ribbon when wrapped to cover the shank as opposed to trying wrap just a black and white hair in close touching turns to get an exact zebra stripe effect.
Here's a pic of a "Moose Midge" I tied up for the midge swap. I've had a pack sitting around for 20+ years, and thought I'd finally put some of it to use. (besides a few sets of antennae on shrimp flies).
Since it's designed to be fished sub surface I wasn't concerned about weight so it's covered in a UV light cured acrylic resin (Big Bond) -- epoxy or several coats of Sally Hansen's Hard As Nails would also work (but they're a bit messier and you'd have to turn the fly while the epoxy of Sally's dries so it all doesn't sag to the bottom of the hook while curing.
