Because the original tutorial includes a lining, which hides all inside raw edges, it was necessary for me to find a solution for the pre-quilted fabric that Mom chose. It created an inside raw edge that would indeed be quite unsightly. So, when I mentioned that to Mom earlier, she bought some 1/4" bias tape, which fixed the problem nicely. (I once tried to reverse-engineer a Vera Bradley clutch of Gabriela's, and I saw that this is part of her design method.)
Mom was so pleased to pull her tote from the gift bag we presented to her at lunch. We had a marvelous time. If you're in the Pittsburgh area, you must try Iovino's Cafe in Mt. Lebanon. After lunch, we headed to Cold Stone to pick up her ice cream cake, then returned to our house to find that my dad and the boys had built a fire in the fireplace. They know that this something I particularly appreciate.
My parents stayed for dinner, and we presented my mom with her final "gift" - a letter I wrote to poke fun at some of her amusing traits. Morgan made it so that Mom can add it to the scrapbook we made for her a couple of years ago. (I posted more birthday photos here.)
