I have lost count of the number of crocheters who like my brioche hat and tea cosy patterns but don’t knit and have asked for a crocheted version. I put my thinking cap on and fiddled around a bit and this is what I came up with. So just for you folk who wanted it in crochet, here it is - finally.

yarn is held double throughout

The crochet instructions are English style, not U.S.

The resulting hat does look very much like knitted brioche stitch.
