Relax, we all look at our work and say I should have done this or I could have dont that or look at that point. The non-quilter's in life say WOW!
Dont feel bad I just made and posted a pic of a queen I thought was perfect, the best I ever did. My mom stopped by and said it was gorgeous and then innocently said is that supposed to go that way....sure enough I have a square in backwards--dead center in the quilt.
I did not see it, the LA did not see it. It is in there to stay and I think they call that a humility square! Now every time I look at the quilt do I see it...yes I did initially but now I see the colors and the quilting.
Cut yourself a break.
