The next hat I knit was also a beret. The pattern is called Urchin by Ysolda Teague and I used a discontinued Classic Elite yarn called Bravo. It's a bulky yarn and it looks like a fluffy mohair yarn twisted with a thick rayon thread. I was afraid that the hat might be a little itchy, but so far, no complaints from the recipient.
The last hat I knit is called Randi. Since the pattern calls for bulky yarn I had to make some changes and calculations so I could use up some leftover Cascade 220 I had in my stash.
