What's your favorite way to mark your garment pieces?

I had a hard time transferring the darts and dots from my pattern pieces to my colorful fashion fabric. I tried tailor's tacks. They came out. I guess I need practice on that particular technique.

Then I tried tracing paper. It didn't show up well. At all. (And it seems rather brutal to the fabric!)

Next, I tried a marking pencil. It didn't work very well either. Hard to apply. Not really visible.

What do you find works best?
