I'm sure a lot of us have used buttonhole for many things over the years. It was one of the first stitches I learnt as a child making a table runner on 11ct Binca fabric aged 7 using wool. Nowadays I use it a lot to stop fraying on the edges of fabric and as a cute stitch for some of the quilt squares. It's great as grass on samplers as you can vary the length easily whilst still having the ground.
Here's what I've done with my buttonhole this week:
Sunbonnet Sue is back but with a buttonhole ribbon on her bonnet and apron.
I've used the stitch to hold down the bottom of the ribbon from last weeks stitch and also using 2 shades of brown to form the bottom of a muddy field.
