(You need that so that youve got the room to manipulate that binding a little bit.)
Next, place the other unsewn length directly on top of the other, creating an overlap.
Take a ruler, find the overlap, and go over two and a half inches.

Once youve found it, take a pencil or any marking tool and mark it.
Get your scissors and trim the excess binding right on the mark.
(You mustnt twist those pieces because youre going to end up with a twisted binding piece.)

After this, get a small ruler and draw a diagonal line where the two pieces meet.
(This is the back or the wrong side.)
Secure this with pins on each side, then take it to the sewing machine and sew it.
After sewing, trim off the excess.
Finger press the binding down or iron it.
Now, go ahead and complete sewing the rest of that seam.
