Yarn and hook: sport yarn of your choice and colors (I love working with Phil Cotton #3 and Tango) and a 3 mm hook (UK11) (US 10/3). Note that you can use whatever yarn size/ weight (and relevant hook for that weight ) you like/have at hand. That will only influence the size of your flowers. Hence, smaller weights will yield tinier flowers, heavier weights will yield bigger flowers.
Stitches (American terminology): chain (ch), slip stitch (sl st), single crochet (sc), single crochet 2 together (sc2tog), half double crochet (hdc), double crochet (dc).
Other: tapestry needle for weaving ends, sewing needle and thread for sewing the filaments, and scissors.
When you are done adding flowers, ch50 and then sl st in the 10th st from hook to make a loop. Try to see if the leaf goes nicely through it. If the loop is too big, than reduce the stitches for it (instead of 10, try with 8 or 7).
