Or at least I think that is what you would call it. I used the same binding on the inside that is on the outside edge. I saw a quilt like this in a magazine many many years ago. I originally made it to hang in my bedroom, but it is currently hanging in our Family Room. I love quilts that are red and white.
Yes, it has a signature mistake as every one of my quilts does. There is always something that I don’t notice until it is complete. This one has one of the inner bindings totally off. It towards the bottom right, but may be hard to see in the photo. It wouldn’t be my quilt unless it had something out of place or not quite right.
