question about grain direction
I am making a quilt for my baby who is due later this fall. The block I have chosen is a double friendship star with the center square being a diamond (square on its point). (I don't know if there's an official name for this block). I understand you are supposed to make all the grainlines run the same direction, but how bad would it be to make this one square different from the rest? It woudl be so much easier to just cut a square, then add triangles to the sides (which would make the grain of this square be diagonal), rather than cut a bigger square, cut away the corners, then add the new corners in the correct color. It's hard to explain, but I hope this makes sense. The entire block is 9" finished, so the square in question is less than 3 inches in size. What do you all think? I'm torn. Thanks!
