Well ladies first of all thank you so much for your feedback. I have finally found the problem. At some point I must have inadvertently hit my needle position button. It was positioned to the left. I always so to the right edge of my presser foot and that gives me my 1/4" seam. It was only a slight variance (1/8") but after you have joined that many squares it adds up of course. It wasn't even visible to me when I looked at it but once I started measuring my finished squares I noticed the mistake. So, I have taken all 5 squares completely apart and started all over again. I don't need to tell any of you quilters how frustrated I was trying to figure this out. Thank you again and happy quilting everyone.
