Made this while waiting for my 650 to arrive. Materials used:
-Remnants from a worn-out pair of jeans
-Embroidery thread
-Heavy-duty corrugated cardboard to provide stiffness and a bit of drop-resistance
-Bits of a felted sweater on the inner surfaces.
-Some leftover ribbon
Still need to add in straps to secure the reader once it gets here. Not perfect, but it's free and I like it better than the sony cases
