This is another Sunshine Wristlet using navy cork and cotton fabric. It's a FREE pattern offered on CRAFTSY.
I 've added a shoulder strap to the bag as well as 6 card slots inside. I left the back of the card slots open, so it's a slip in pocket which can hold a cell. There's also a zip pocket, so lots of room for your essentials!
Instructions for the card slots and the slider are:
Clemantis Card Slot Pocket Hack. by Debbie Hunker. Debbie also has a tutorial on the Clematis, and shows how to attach the shoulder strap near the ends of the zipper, so the D rings aren't standing out on the side of the bag!
