For those kids or grandkids that keep you on your toes, have I got the hat for you! My mom came up with this idea and I loved it. Very easy, in the round construction, the horns are added on after the rest of the hat is finished. There is a set up row for the horns in the top decreases. The horns are knit using double point needles. When finished the hat has a 17.25” circumference but I photographed it on a bowl that is 22” around so there is a lot of room for stretch!
