They do look great!! Nice job. As far as the glue, that's really the only "art" there is to fletching arrows, the right amount of glue. You're using just a little too much. It takes far less than you would think it would.

Think of it like this.....Run a SMALL bead of glue down the vane. Even if you miss a tiny spot here and there, don't worry about it. When you mash the vane to the shaft that glue will all even out, giving good coverage. If you use too much it's gonna run out the ends.
