Yes, it is designed by Jenny Williams and is available on Craftsy. In the pattern, she gives two options for a knitted handle but I chose to line the bag and used leather handles instead.
I love this bag, actually I saw the original but with the details of the handles change completely, also the shape is slightly different, do you follow exactly the pattern ? congratulations is just gorgeous. Ill try to make it =)
I did follow the pattern exactly so perhaps the difference in shape is just due to tension. The photo does make the bag look more as though it is a flat, envelope shape but it does have an oval base. I thought the knitted handle might stretch as I only planned to lightly felt the bag but I did need to line it in order to have something to sew the handles to. I was really pleased with the way it turned out, particularly as I made it as a gift!
