I started with the short sleeve from one of Jonathan’s worn out shirts. I folded the hem together and took the strapping from a water bottle holder that I don’t use and sewed it on to the base and tacked the shoulder strap in place.
The extra fabric above the pocket folds down and forms a protective flap that is held in place under the strap.
I then ran elastic around the edge of the bag to hold the center pocket together. I now have a shoulder bag with three pockets big enough for my phone, keys, hankie, and beachcombing finds. I can keep the sand off my phone by always putting it in the same pocket and always putting my beach finds in the main pocket.
I have another project in mind, but now the internet is back and I have to catch up on writing.
