Materials
Bulky or Extra Bulky Weight Yarn (way less than one ball will do)
5.5 MM "I" or even "J" crochet hook (Check your gauge hooks on preference)
Craft needle
Notes: You can either work continually in rounds or Slip-stitch your final stitch to your first in the row and Chain 3 to count as first Double Crochet stepping up in your next row (my example steps up each row). Also, I used a fairly bulky acrylic which gave a finished size of about 4 inches or 10 cm diameter, they're one size fits most unless you'd like them bigger or smaller.
