I wanted a hat to match a ripple scarf, but all the patterns I found started with magic rings and circles, not ripples. This hat starts with a foundation chain, but is worked in rounds. This lets the ripple start at the very top of the hat.

This hat makes a thinner fabric, due to stitches being worked in the back loop.

There are pictures showing how to turn the foundation chain into the top of the hat.

This hat matches the 5 Stitch Ripple Scarf and can be purchased together as an ebook collection.
