You will need 2 skeins of Vanna's Choice yarn, a little leftover of another color for the flower, 1 large button, size US L/8.00 mm and US H8/5.00 mm hooks. This pattern calls for 2 strands of yarn, you can use two different colors or two same colors. I used brown and beige for this hat, and mustard for the flower.
Stitches used: ch, sc, dc, sl st, puff stitch for the flower. Includes instructions how to do a puff stitch.
One size will fit most.
