I can't be doing with hand stitching a binding, so my binding starts as 3.5 inches (gasp!). This means the triangles left over from each binding join make these 2 inch half square triangles....and when I've collected enough of them, i do something like this.
This time i did raid my other scrap bin to make loads more.
 
Of note: the discoloration in the binding is noted and intentional. I'm a bit mad for vintage muslin sackcloth and I've left the evidence of aging as is.
