Carry your essentials in style with this mathematically-inspired wallet. The dimensions and color striping use the golden ratio to create a balanced design.

Construction notes:

• Make a long rectangle twice as long as the finished piece
• Fold in half, seaming the bottom and short side
• Hand-sew a zipper (and optional lining) to the top to complete

Gauge doesn’t matter too much here. You can also use any other t-shirt-style yarn.
