I sew the excess down neatly by machine. I fold the bottom edge under twice to make a smooth edged sleeve.
In this photo the sleeve is folded up so you can see the sewing lines. The sleeve
and backing are both white, and the blue you see is the binding. The red line
shows where I attached the binding and the green line is where I attached sleeve.
This shows it with the sleeve folded down.
I sew the bottom of the sleeve down by hand, being careful not to let my stitches go through to the front of the wall hanging.
And here it is with the binding all finished.
Here is the same sleeve with a rod inserted. (The pocket on
this wall hanging is larger to accommodate a larger rod which accompanies the quilt
hanger in my family room. The rod on that hanger is much fatter than the rod shown here.)
Here is a different wall hanging with the completed sleeve, with a rod in the pocket.
