You said you cut the fabric wrong. Do you mean that you cut it in the wrong direction? Like with or against the grain? Which ever, I don't know why you can't use it either way. Don't we all make big mistakes? My mother, (bless her) was a quilter, and so would always tell me that the only one that walked this earth, that could make a prefect quilt, was Jesus himself. Makes me feel good when I mess up!! And I do it plenty. Good luck!!!!
