Scientists and people passionate about science are a diverse and multifaceted group of individuals. To reflect this diverse nature we are not encouraging a single hat pattern or design.

Here are a few free patterns to get you started all with various degrees of difficulty. Click the images for links to PDFs and websites.

These are just a few knitting patterns! Other resources we've found great for hat patterns:
