I don't have a picture, either, but this should make you feel a bit better.
One time I was making a quilt with 3" squares and one of the fabrics looked like dark aqua from one direction and nearly black from the other. Not realizing that quilting cotton could have nap, too, I didn't see it until I was nearly done. It was in the middle of the quilt, looking for all the world like a black hole. So, I bit the bullet and very carefully loosened and tied off the surrounding seams. This took a Long Time because the quilt top was big and bulky.
Then, I very carefully reset the square and restored the seams - the Very Same Way.
Hugs,
