This cute wallet works up quickly and is a great introduction to simple colorwork. The pattern was inspired by the viral checkerboard stitch pattern.

This pattern is suitable for adventurous beginners and intermediate crocheters. I suggest you try it as one of your first colorwork projects, as it is quick and relatively easy.

4.00mm crochet hook
Scissors
Needle to sew ends in
Button (optional)

Abbreviations (US terminology)
ch - chain
SC - single crochet
DC - double crochet
Sts - stitches
CA - color A

A note on color work
To achieve the checkered pattern on both sides of the wallet, I worked of the yarn of the opposite color to the one I was currently working with. If you need more help with this technique, a checkerboard tutorial from BrittanyAliceCrochet can be found at:

Keep in mind the tutorial uses half double crochet, meanwhile my pattern uses DC. It can be quite tricky to grasp at the start, but you can do it!
