A great beginner knit in a simple garter stitch, this is quick, easy and satisfying. For the motif hats you can add the designs either using the Intarsia method of knitting or by using Swiss Darning (or Duplicate Stitch) afterwards. In fact we find Swiss Darning leads to a more pronounced pattern with more impact and is how we produced our samples.
We love the idea of reversing the colours if you want to create two hats.
Note: the motifs are deliberately upside down as the brim is knitted and then folded back so the motifs end up being the right way up once folded.
