The only stitch you will need to know is the single crochet, which is the most basic crochet stitch. There are many places to learn how to single crochet, but I learned by watching the knit witch on YouTube. Lion Brand Yarn has helpful crochet lessons as well.
Here are the materials you will need :
US G-6 (4.0 mm) crochet hook
black, white, and red yarn
black embroidery thread
Abbreviations: ch = chain; sc = single crochet; st = stitch
