I cut my binding 2 1/4 inches wide:
And then attach it to the quilt using a generous 1/4 inch seam:
Once it is all attached I give the binding a good press before I start hand-sewing. I put my ruler next to it today for this shot. The seam is 1/4 inch and the binding is half an inch again:
This means that when you fold it over it just clears your stitching line. I like this form of binding because you get a nice full binding that is the same size on both sides. For the neat freak in me that is ridiculously satisfying!
This is what I am working on. It has taken me months to decide on a colour for the border - lots of people gave me feedback when I asked for help but there was no definitive winner between light and dark! Today was the day I bit the bullet and chose light. A bit of hand sewing and it will finally be done.
