I designed this to wear in the March for Science on April 22, 2017. This hat pattern features a circuit with a battery and 3 resistors in series (to increase the resistance). Resistors are commonly used in electronics to slow down the electric current - the 4 vertical lines on the hat represent the battery while the zig-zag represents resistors.

This hat would be perfect for your favorite electrician, engineer, physicist, or other nerdy scientist in your life.

This hat is designed for worsted weight yarn.

IMPORTANT! I have a very loose knitting gauge, so make sure to test your gauge to ensure the proper fit! Most knitters will have to size up several needle sizes to achieve my gauge.

Feel free to contact me with any questions.

Update 2/27/17 - To see this hat in action, check out this “Show and Tell” video: https://youtu.be/leIZjIDM03c

UPDATE 2/12/17 7:30 pm PT - I had an error in the original pattern. At the end, there should be 6 stitches remaining on the needles to weave the yarn through and I wrote 6. I’ve updated the pdf (now linked on the website)

Update 2/14/17 - Keep checking website for the pattern, as I am continuously updating it to make it more user-friendly to new knitters. :) There is also a March for Science - Official Knitting group here on Ravelry and a March for Science - Official Knitting and Crafting group on facebook. Join in the fun!
