Resurrecting Old Crochet Hats
In the mid-1980's I remember my Polish mother-in-law, Henryka, showing me how to crochet in a spiral and how to add contrast surface-crochet. [Originally the surface-crochet was made using a slip stitch, however, over the years I have changed that to (slip stitch, ch1) instead, which I think is way better].
