I was inspired by a vintage pattern published in April 1933. It was the pattern of a hat called “chéchia”, a kind of fez.
I based it on my teapot, but with the drawing included on this pattern which shows you the different measurements you can adapt it to your teapot.
The “body” is knitted in rib, the top in the round in stockinette stitch. You will only need a skein, 3mm needles and a few hours to make it.
