I realized after I had cut out the material that I might have difficulty sewing the pieces of my bag together because the seams would be down the middle and there weren't side seams.
But that figured itself out when I started pinning the pieces together and one went inside the other!
I think both of them turned out fine and I should make some more some day. My sister's bag is on the left and mine is on the right. As you can see my handle is narrower and that is because of the seam down the middle.
