I only saw it because you mentioned it.
Hard call on this one because it blends so well.
The quilt is absolutely gorgeous!
This has happened to me with one of my own quilts and I didn't fix it. Whenever I see this quilt in October, I always focus on the mistake and it bothers me.
You're giving it away as a gift and the mistake is not noticable. Like I said, it's a hard call.
