* put your sugar syrup (or whatever you're using to prime it) in the bottling bucket first
* siphon it as "quietly" as possible, so as not to introduce bubbles/oxygen into the wort
* stir the priming solution with the wort gently, and stir it a couple of times while you're bottling.
If you didn't have a bottling wand (the little thing you attach to your siphon tubing that starts beer flow by pushing down inside the bottle and stops when you pull up) buy one! It's only a few dollars but saves headaches and most importantly beer.
