This wasn't so hard to finish. What happened is that I made it last year (using this tutorial) right before we had our little boy...and I tried to buy plastic handles for it. Well, they were too small and I couldn't attach them the way I had envisioned.
Also, plastic handles can't be slung over one's shoulder while juggling a baby/toddler, diaper bag, and possibly one of the baby's shoes. So I got some scraps and sewed a ribbon down the middle of each one (to keep the handles from stretching), sewed up the handles, turned them, and installed them! Easy. I like how it turned out!
