I'm done 4 of the big blocks, have webbed another 12 together vertically, and did all 40 sashes. I have a lot of ironing ahead of me as I'm trying to follow Bonnie's advice on what to press in which direction. Slow going as every time I press something, some seam somewhere else ends of flipping. I'm trying to slow down but really anxious to get this floppy together. Did anyone else have issues pressing the big blocks? Maybe I should cut the webbing and press since only 5 small blocks might be less likely to result in seams flipping.
