Took a while to make this. I started out with a pattern but it was all messed up, so ended up designing most of it myself! But My DH is Happy.
The bag has a Insul-Brite layer to keep beverages cold or hot. And a half layer of iron on plastic for so not to get the bag wet from sweat water. He loves it. I am making two different types also.
Not good pictures but you can see this one.
Came out dark. Sorry
Strap is ajustable but I made it a little to long. I have to shorten it about 5 inches.
