This crossbody cell phone bag can hold a device with a measurement around 8cm (3 inches) wide by 16.5cm (6.5 inches) high. The I-cord handle is 1.7m (42 inches) long.
The broken seed stitch reminds me of the scales on a mermaid tail. It looks complicated but is actually quite straightforward. It is created by alternating two colour yarns each row while knitting in the round. It does not involve stranded work, intarsia or fair isle.
