Now, just flip the two pockets inside out and flatten everything out. Using the graphic on the right as your guide sew two sets of two lines from top to bottom as shown by the red lines in the graphic on the right. We measured with a measuring tape and ironed in a crease so that we could make a accurately straight sew-lines. These two lines should be about 1/4" (6mm) apart so that you will be able to fold the wallet without the edges of the disks interfering with eachother. The 5 1/8" (13cm) will be enough to securely hold the disks but rendering them easy to insert and remove.
