Hope this makes you feel better. I'm making a quilt with 16.5" blocks. I cut one whole side of my block wrong. Grrrr! Went upstairs, got my jammies on, woke up in the morning and had a quick solution. Also, my GGD cut a small hole in the quilt I made for her so I cut out some hearts and appliquéd them around the quilt and it looks like that's how it should be. I was sick when I first saw the quilt! It happens to me way toooooo often. You have some great tips. It will be great!
