Just a thought... Most of the posts I see on the board by quilters that say something about the mistakes they made in the quilt pictured are followed by comments from fellow quilters who either can't find the mistake, or say that they thought that the "mistake" was an intentional design intention. Even the ones who see the mistake usually say that most people wouldn't know it was there if it hadn't been pointed out. If it's frustrating you too much, put it away for a while (sometimes years LOL) or toss it, or donate it.
