...yep, that's exactly what it was, while I was wrestling with it. WRESTLING! Literally. The pattern and directions are not exceptionally difficult. It's the layers upon layers of fabric, interfacing and super stiff peltex. I broke two machine needles, bent endless pins and drew blood twice while trying to tack the dividers into place by hand.
Amy Butler Blossom Bag, I read this review. I second it 360% and then some.
I tried to take a short cut and used fusible extra-stiff Peltex instead of extra-stiff Peltex + fusible interfacing. At first that idea seemed to work just fine, until I had to turn the bag right side out: the fabric started to become wavy and puckered. I am not sure if I measured incorrectly, but the snap did not line up at first and I had to patch up the holes and cut a set of new ones.
Please let me know if you made one. I'd love to hear what you think.
