Sheryl gave us a little diagram showing that most people scan from the center to the upper right, to upper left, to lower left, back to center and on the upper right, to lower right, then back to center. Is this what you did?
In Sheryl's talk, she said she would start quilting in the lower right near the center because that is the last place most people look. This gives her a little time to get in the groove of the motif she is using and if there are any less than perfect elements, they are not as readily noticed.
When I set my four acorn blocks together, there was method to my madness. The first block I did ended up being slightly different than the other three. I struggled with appliqueing those deep valleys on the leaves, as you might remember here. And my placement of the applique pieces on the background fabric was a little too free-style. I sent out a cry for help and got some terrific advice, shown here. One of the tidbits that really came in handy was an easy method for accurately placing the pieces on the background fabric. You can check that our here.
I toyed with the idea of remaking that first block. Then my sister reminded me of the Amish rule of quilting: only God can create perfection, so mistakes are okay. This was just the advice this recovering perfectionist needed to hear! So I set these four blocks together with Sheryl's diagram in mind and put that "slightly different" block in the lower right corner where hopefully its uniqueness didn't scream out so loud. I know it is there, so it is the first thing I see. Let me know if you noticed it, or if you had to go back and look at it again.
