Those threads are invisible ... until you take a photo of them and then they're there for the world to see! These are beeyootiful, Freda. :o)
The kitty in the window!!! This really made me chuckle. Ok, I have to say it....Purrfect! And like you, I spend way too much time matching fabric ;-/
The threads are from the raw edge of the fabric in the seam allowance. Wild threads! Love your yellow, pink and blue houses. Sweet.Hugs
Love the one with the kitty in the window. You'll have your grandkids searching for that one each time they see the quilt once it's finished.
