You will need - outer and lining fabric (I used velvet and satin for my jewellery roll), iron-on interfacing, two co-ordinating zips, co-ordinating thread, a small piece of velcro or a metal snap.
Step 1: Cut out fabrics and interfacing
Lining fabric: 20x30cm for lining, 20x40cm for pocket panel, 2 pieces 20x20cm for upper zipped pocket, 2 pieces 20x10cm for lower zipped pocket, 2 pieces 6x30cm for ties
Iron on interfacing: 20x30cm for lining, 20x40cm for pocket panel
I only used interfacing for the pocket panel and the lining as they were the bits I felt needed a bit of reinforcement but you can reinforce as much as you want.
Press flat the lining and outer fabrics, and iron on the interfacing. Press ties in half lengthwise, then fold raw edges in and press again.
