This is a quick hat using two colors of Knit Picks Wool of the Andes Sport. A lifted stitch creates the lattice-like pattern on the brim. I thought it looked like frost on a pane of glass so I named it Heladas Hat. (Heladas is frost in Spanish and is pronounced ay-laud-us with the accent on the second syllable.) An easy pinstripe is worked to the crown.
You can buy Heladas for $4.50 through Ravelry.
