It took me a week to complete this project because I never had much time on any given day to work on it. If you had a couple of hours available to focus on the project, it would only take one day to finish this.
Designer Claudia Bostic shared her free pattern to make these Puff Hats in the files of the Addi Circular Knitting Machines group on Facebook. This design is a good alternative for making beanies to fit larger size heads.
Since this was my first attempt at making the pattern, it didn't turn out 100% perfectly, but it's not bad for a first try. I attempted to use the kitchener stitch to graft the ends of the large (bottom) tube, based on instructions from Yay for Yarn's tutorial on YouTube. (Grafting the ends of the large tube is an optional technique; you can join the ends of that tube using any method you prefer.)
