To use superglue and freehand fletching, I always tack down the back end of the fletch with a tiny dab. Then I go to the front of the fletch, pull it tight, add a bit of off-set, and another dab to the front. Once I have all three fletches where I want them, I go back and lift the quill off the shaft and run a bead of glue along that. If you stretched it properly when tacking it will snap down against the shaft and sit nicely.
