Binding with Bias - Method 3 - machine -front first

Applying bias to the front (right side) of the fabric first.
Open up bias, line up the edge with the edge of the fabric.
Most commercial bias binding has one side folded slightly bigger than the other to make this method a little easier.
The edge you line up to the edge you want to bind should be the one that is a little smaller.
Sew along the crease of the bias with a straight stitch.

Now fold the bias to the back.
The loose edge of the bias is underneath.
You need to roll the bias to the back so that there is more bias at the back than the front.
This time we sew the bias down from the front.
Along the ditch created by the previous stitching.
Use a thread that matches your fabric not your binding.

Pros
This method is neater than Method 2
It can be quick.
It can be very neat as the stitching becomes hidden in the ditch.

Cons
Fiddly
I often miss catching the binding at the back. Resulting in either unpicking and re sewing or sewing the missed section by hand.
