Funny to read this topic just this week. I was working on a Hunter's Star block and boy oh boy did I have trouble with pressing those seams. First I would press all the blocks towards the darkest triangle which I thought would give me opposing seams when sewing it all together but that really didn't work. I had a devil of a time and actually wound up sewing any which way and then pressing the heck out of them from the right side. I sure wish I had asked about this before I started. This was supposed to be fast and easy but turned out to be slow and hard. I'm at the finish line now and it is beautiful but never again.
