I mixed it up by crocheting the scarf and knitting the hat. The hat has a floppy brim and the scarf is long, thick, and heavy and has a woven look.
I made this from 3 partial worsted-weight skeins
Size 8 circular needle (hat)
Size 8 doublepoint needles (hat)
Size H crochet hook (scarf)
Time: hat 3 hrs, scarf 6 hrs
