Start by making the foundation chain with 30 stitches (or any multiple of 2) with crochet hook number 3.5 mm.
Work in rounds following the crochet diagram from the bottom to the top and from right to left. Repeat row 2 at least 20-25 times or as many times as you wish.
TIP: To obtain a more professional finish, replace the foundation chain and the first round for a chainless foundation treble crochet (ftc).

Row 2 – 25: 3 ch, [ 1 Frtr, 1 Brtr ] x 14, 1 Frtr, 1 ss. (30)
Fasten off.
