After having done it once, and seeing that the two pockets I’d made weren’t enough for the cards I was starting to need to carry (driver’s license, M & S card, oyster card, credit card, some cash and a few business cards), I decided to make a second version with more pockets. I’d especially liked the diagonal pocket, so I made two of them.
I cut out the pieces carefully, even though I didn’t bother measuring them.
I then pinned the edges of the pockets so I could get nice angles on them.
This side will have one full-length pocket in which I will hide the oyster. See it never needs to be removed to be used, it can work through the oyster card holder’s fabric, which means I can put it in the nearest-to-the-outside pocket, and hide it completely from view quite safely.
After stitching all around the flipped “innards” of the holder, I cut the edges closer to the seam with crimping scissors. This means that when I flip it inside-out, the edges will be less poofy. (what do you mean, “poofy” isn’t a technical term?)
As I was making it, I decided to add a strap. I cut a length of fabric about 5cm wide in the diagonal of the fabric to make sure it will have some extra stretch, and stitched it inside-out along the long edge. This made for a tube, which I trimmed close to the seam and flipped inside-out to get a simple strap. I then anchored the strap between the “innards” (green pockets of the inside) and the blue rip-stop canvas outer, and made sure it stayed put when I stitched around the edge.
This is the oyster card holder v2.0 in use.
