Inside lining: about 1 metre of black lightweight fusible or iron-on interfacing. Get the good stuff. The cheap stuff we purchased only fuses in patches, if at all.
Outer lining: about 1 metre of black foil jersey, or similar fabric.
Coloured strips: about ½-1 metre each of blue and gold metallic-look fabric (we used foil jersey).
Matching or ‘invisible’ sewing thread.
A large sheet of paper, or some smaller sheets taped together.
Optional: some Hobbyfill, wadding or cloth suitable for stuffing.
