I press to the darker or solid print as the case may be. It took me a long time to actually do it though, mainly because I was use to the clothing thing too...where you press open. I didn't like the way corners looked on the back when I pressed them open, so, I forced myself to the side thing. It may be for a silly reason, but its a reason that's always stuck with me; Grandma taught me (especially with embroidery, but it translates to most things) if the back looks neat, the front is always sure to. It doesn't always work out that way with my blocks, LOL, but I'm getting there slowly but surely.
