It's all about forgiving yourself.
When something happens on a quilt top, something that is super noticeable then we make a decision, Do we point it out or not.
Here is what I told a student who asked me that same question:
If the quilt is 6700 square inches. Then your faux pas is 1/6700 inch of that quilt.
Would your friends be deliberately looking to see your mishap, maybe you caught the dark seam edge with 2 stitches of light colored thread.
Most bobbles and wobbles blend in. And you know I believe in creating patterns, designs and techniques with "wiggle room" so you never have to be perfect!
You are probably harder on yourself than anyone....so forgive yourself and give your machine a big hug.
