To be successful with this pattern you should know how to start with a ‘Magic’ ring, Crochet in back loop only, and Crochet in bottom loop of chain.

La Croix Pattée is a pattern for thread crochet from Cara’s Handcrafted Crocheted Ornaments
(Also known as St. John’s, Maltese, Regeneration, Fishtail,
Campaign, Forme and Iron Cross.)

A friend asked if I could design an Iron Cross to use as an embellishment on a hat for a teenaged boy. I think this design has broad appeal and can picture it being used for a lot of different decorative applications.
