I sharpen sitting on a desk, sitting in a desk chair. That's the way I started years ago, never thought of changing it. My stone is on a semi-wet towel on the desk. If I need to get new water on my stone, I take the stone of and put it a little tray with water that's on the floor next to the desk. I like to sharpen with music on, I pick whatever I feel like listening to at that moment. I sharpen in the living room, my wife hates it when im doing coarse stones
After years of flipping the knife (I always had more trouble with the side with has the edge towards your body), I recently (few months) switched to switching hands for the left and right side. Practised long enough untill it started to feel natural. yesterday I tried flipping again, just to try. I can't even do that anymore.
It is all wrong. It works for me.
Some time ago while in the best of my concentration (you know, when mind and body are one. When you forget about everything around you and are completely one with the sharpening) I catched myself on a new habit:
I lock my elbows and shoulders while having the arms and hands very loose and I move my upperbody to make the sharpening motion. I even turn, and raise this way. I find I'm having the best results lately and I like it. I can really feel what the knife is doing on my stone. The biggest improvement is the nice sharp/straigt edge I more often get around the belly of the knife, especially on Western style. The belly was always the most difficult for me (uneven sharpening), and when I raise and turn my upperbody to follow the knifes curvature, I get way more consistent results.
The wife says it looks kinda strange
but she likes the knives Im providing her
