I love stitching over-one...but I don't think I could ever do a really large piece that way! The details just come out so very beautifully and (as an extra side benefit) framing costs are less! LOL!
This is Blackbird Designs Loose Feathers #10: Autumn Silhouette. I chose a darker linen with a cream-toned hand-dyed floss. I had to adapt the acorns that were done in a satin stitch, and I loved the way it turned out. I did this same design in a green over two on a much lighter linen, but the over-one is by far my favorite. Including the frame, this measures 6 3/4" x 5 3/4".
