See the closure tab? It's a power button.
Aren't those little robots on the fabric adorable? I used a tutorial from VeryPurplePerson here. I have sewn a few before using this tutorial and made some modifications so that it wouldn't need the binding on the sides. The binding makes it a bit too wide. This time for the card slots I used a combination of the measurements given in the Necessary Clutch Wallet Pattern from Emmaline Bags adapting them with the tutorial. Also I changed the way to attach the closing tab and added a removable wrist strap. Little by little I've been getting to a set of measurements and way to construct the wallet that I really like.
Having a wallet so cute will make sure make her smile every time she takes it out from her purse to pay for something. :-)
