Don't you hate that! I was doing the final starch and pressing of my quilt back when I noticed a dark thread. I don't know how I missed it before but it is glaring at me now. At first I thought it was a loose thread but no, it's woven right into my cream floral. I bought 2 m. off the sale table and if I'd seen the flaw before cutting my backing to length, I could have avoided it. I am glad I didn't pay full price for it and I will applique something over it but still.....Thanks for letting me vent, I feel much better now.
