I have to share this.... When pressing an intersection open where 4 or more seams intersect, dip your finger in water and put a drop at the point where all the seams meet (while holding the seam open) and then press the seam open. I used this tip on 4 patch blocks today and it worked so well that I dug out a few UFOs that had already been pressed in one direction and repressed them with open seams. I usually overpress everything and sometimes I scorch stuff....I want it to lay flat! I won't be scorching my blocks anymore thanks to this tip ! :) :) :) :)
