The size of the finished clutch bag is 30cm (12”) in width and 20cm (8”) in height. The total length of the handle is 40cm (16”) folded in half.
As a material/yarn, I used leftovers the soft t-shirt yarn I had from another project. But it is possible to use practically anything, what suits your needs and the corresponding size of the hook (I used 5mm/H/6).
