This is a little sewing project that I patterned myself. The bag is 10 1/2" long and 6 1/4" wide. Once you cut two pieces of fabric out on the fold, you whip stitch three of the sides, making sure that the good sides of the fabric are touching. Then you whipstitch the top two edges, attach a strap that's however long that you want it to be, turn it right side out, and be done! This bag is perfect for when you only need your wallet, your keys, a small notebook, and other smalls.
