I found that actual yarn has a tendency to stick to itself. I tested both yarn and string side by side and the yarn would twirl around and stick to itself or the yarn above it, ruining the test.

As I have mentioned in other places on this forum, it seems that an easy way to test hard to reach areas such as inside wheelwells and under bumpers would be to purchase a small web cam and run a wire to a laptop within the car.
You could then save a video of the test. The best thing about this method would be that you do not need a chase car.

Any longer than 3" and the yarn seems to flutter due to the turbulence of the yarn itself.
Also it might be a good idea to plan out the layout of the yarn since you don't want the turbulence of a fluttering piece of yarn distorting an area that is smooth.

Edit : I meant any longer than three inches on the length.
