its really very easy. you just put fusible thread in the bobbin and sew the binding strip to the front like normal.
then when you turn the binding strip over to the back instead of having to put down glue to hold it in place you just iron the edge of the binding strip to the seam line on the back.
its a light fusible that will hold the binding strip in place while you SITD from the front.
the fusible washes out or wears away with time so it doesn't make the area stiff at all.
