I have the book Tilda Studio as my bedside reading at the moment. I've had a go at making the beauty bag pattern from the book. I've recently discovered the zipper foot attachment to my sewing machine, and that made the process a whole lot easier!. Its amazing how much difference having the right tool for the job makes.
The bag came out pretty well for a first attempt, and only took a couple of hours. The padding made it a little difficult to sew the trims on the side at the end. I had to do that part by hand.
