I've made this bag before - you'd think I would have learned. I'm making this one as a gift for a teacher at school who is having her first baby. The problem is the way the bag hangs when it's closed and hanging on your shoulder. I put three magnetic clasps - one on each end and two in the middle, but that's not particularly convenient for a mom who's trying to open the bag while carrying a child. The bag calls for fusible fleece sealed by a layer of fusible interfacing, which I used. I probably should have used Peltex on the exterior panels, but that may give it too much structure. Next time, I will install a zipper instead of using magnetic closures. In the meantime, what can I do? Has anyone ever used boning? I noticed U-handbag sells it for use in purses. Is it possible to install boning after the fact? I haven't yet closed the lining, so could still reach the wrong side of the exterior top edge of the purse. I welcome any suggestions. Thanks.
