Pippus-hat is worked from brim up in the round. The stitch pattern is stretchy so you can block it according to your liking. The crown (top) stitches are bound off with 3 needle bind off while you are knitting so there is no seaming afterwards. The I-cord antennas are knitted last. Pompoms are attached to the antennas.
