Love, love the colors and love the pattern. As for the pressing -- DO NOT run your iron over the seams or any of the fabric!!!! Simply set the iron down, lift and set in another spot. Regular ironing will distort your blocks.
I'm a firm believer in pressing (not ironing) each & every seam; may take longer but your finished product will be much nicer. I know because I've screwed up loads of fabric by ironing -- learned the hard way!
