I could not figure out the instructions for the handle, so I did my own thing with that. It is triple crochet. I thought that stitch would go best with the mesh, and I made it long enough so that it should not be in the way when filling the bag.
I have really enjoyed making this for my niece and thought of her and my mom as I was making the bag. Which is one of the joys of making things for people, I think of them while I am stitching or crafting, or whatever.
I love the mesh look and yarn so much I am making a scarf for myself and will post about that another time.
