The tutorial is simple enough that I whipped this out in a few hours of sewing. I like that the gathering details make it look more complicated than it really is.
I also used the the Gathered Clutch tutorial for this Mother's Day gift for my mom, I just modified it a bit. I pieced the front band, added a back band (also pieced), created uniform pleats, and added gussets for shape. The additions made it interesting and not nearly as simple. But I still love how it turned out.
