Hi ladies, I'm doing a quilt with standard 5x5 squares. I'm using a ruler and rotary cutter to make the squares, they are 5 across so I'm joining each square with a quarter inch seam, so far so good. However when I join each row together I am finding that some squares don't line up properly and I can't understand why not !! They are all cut the same and the seam is a quarter inch on all of them so how is it possible that some of them are out. It's driving me nuts because obviously my lines are off when the squares don't line up. I heard Jenny say on a tutorial about measuring from the peak or the valley but she didn't explain it so I don't know what she ment, maybe this is what I am doing wrong ? Any help would be great please : ) I suppose it could be my cutting but I hope not : )
