Starting in the middle of any side leave an 8-inch tail of binding strip before your first pin.

Fold the binding in half as you go with the right side of the fabric out, so the raw edges are together.

Pin the raw edges of the binding to the raw edge of the blanket all the way down the side. 

When you get to a corner follow along with the pictures below. We are making mitered corners, which sound a lot harder than they are. 

Pin the strip until you arrive at the corner. Fold the binding over itself so that it makes a 45 degree angle as in the photo above.

Fold the loose side down so it lines up with the next edge of the O-Wool.

You will have a triangle of excess like this if you've done it correctly. 

Once you've gotten around the entire blanket leave another 8 inch tail at the end. 

Using a Hera Marker or chalk mark 1 1/4-inches from the edge all the way around the blanket.

You're ready to sew!
