Marking flap position
For those that have marked their flaps for position can you share your marking method. I am a big supporter of the KISS principal so I am going the no positioning system route.

Permanent marker lines drawn on flap at selected intervals on LH side. Quick look out to the left and count how many lines you can see (1, 2, or all 3). It has worked great for 6 years.

Pete-
I'm like you. Less is better. Full flaps is 12 seconds down, half flaps is 6 seconds down. I only use no flaps, half flaps, or full flaps. If for some reason I forget to count, I can now visually tell when they are at any of those three positions.
If you do want a visual indication, just use a sharpie where the outboard leading edge of the flap meets the wing top skin per Philip's suggestion above.

Like you, I kept mine Van's simple.
No marks of any kind because I found out for landing there are two settings, up and down.
Abeam the numbers I drop in all the flaps and trim it and keep that speed until the flair. Very simple and an easy way to make consistent approaches.
For soft field operations I lower the aileron and drop the flap to match it.

I printed an adhesive label with 15, 30 and 40 on it in the right spots for them to line up with the top skin. Stuck it on the left flap and covered it with the flap tape.

I use the timing method and also I have colored stripes painted on the flaps for verifying the position. Simple and works great.

I used black pin-stripe tape on the left flap. I have 3 marks at 10, 20, 30 degrees (I think, don't even remember any more). Mostly I count to 3 for each 'notch' of flaps, and just look at the marks for reference.

Me too, I think - I used full down aileron to set the mark. I had used an inclinometer to find different flap positions, then reverted to the KISS method.

Down aileron is 15-17 deg. but that's pretty close!
