Its the Cath Kidston craft bag www.johnlewis.com/231261206/Product.aspx?source=63258.
Its just the right size and shape for all my crafty sewing kit to fit into but at £35 its a bit pricey for me, plus I don't like the CK fabrics much. I was just wondering if anyone had done their own and whether there is a free pattern or tutorial out there anywhere for something similar. Thanks.
