I never noticed zipper direction!Her bags' top and front zippers go in the opposite direction from what I need (not sure why?), which is a non-starter for me. I found the lining to be too thin and it slid around (one of my top pet peeves), and I was not pleased with the finish of some of the details - especially the handles. It has probably been 4-5 years though and of these things have likely improved. But I see the zipper direction is still the same. She will customize, but it's not worth it to me when I'm not in love anyway. She has some absolutely stunning leathers, though!
I also don't mind slidey lining . And I love her handles because doing French seams almost everywhere, especially the handles, means no edge paint to crack and peel down the line. It's also just a nice change and impressive how she manages to French seam so much when sewing leather. I sew and I have sewn bags so this style seems really hard and no wonder many just sew up raw cut leather and then wax or paint the edges. But I love all my bags' finishing details so maybe I'm just not set on particular details if I get other things in place that I find hard to locate (style, shape, versatility, handle/carry options, hardware and capacity) to my liking all in one bag and under $400 (and $300 or less is way more like it).
