This is probably old news for lots of you, but I learned this from an expert seamstress this weekend and it made a huge difference for me. When pressing seams open, first press flat to set the seam, then flip and press to one side, then open it up and press open. Pressing to one side first makes it much easier to open up. Prior to this I would set seam, then finger press open - then press. That extra step is genius. Hoping I'm not the only one who didn't know this
