Depending on what I'm working with at the time. If I'm working with bias I use "Best Press"(I use the Lavendar sent but they have other sents. I like the way it smells) But if I'm working with just squares or strips then I always use steam. I always press my seams to one side and usually it is towards the dark. I was taught to not press my seams open because the seams could pull apart in time.

Good Luck.
