McCall's as it was the size I wanted and it was in my stash. I added an extra pocket at the back and a long fabric strap with a clip to hold my keys yet allow me to pull them and use without unhooking them. Picking the fabrics was one of the time consuming elements as I wanted to use my hand dyed pieces. Ended up piecing some commercial pieces to make the straps and commercial for the lining. Oh yes, added some extra pockets inside too. So overall I'm pleased.
Hope you're having a fun, colorful, creative summer! Or winter depending where you are spending it!
