The pattern is the Big Button Beret from the Adventures of the Gingerbread Lady blog, July 2010. http://gingerschatz.blogspot.com/2010/07/pattern-big-button-beret.html
I used the Knit Picks Felici yarn colorway Time Traveler. You know I had to have that yarn. LOL It's special reserve yarn made in Italy and the colorway is only available at certain times. It is fingering weight, 75% Superwash Merino Wool, 25% Nylon, 218 yards / 50 grams. That is just over 1.7 ounces. I used about 1 1/2 skeins which is about 2.5 ounces for my hat. Note I have a small head so you may use more if you work this pattern.
I used an F crochet hook.
I haven't put a button on it though I'm thinking about it. :-)
I tried to take selfies of myself wearing it. I'm not great at selfies. Also, the lighting wasn't great. Of course, the model is not great. Those are my excuses. I am wearing it as a slouch hat. Note the Adipose earrings my husband made for me. :-)
The pattern is fairly simple to work. You just have to keep track of how many double crochets between the increases and decreases. There are lots of pictures to help too. Although I don't often work with fingering yarn, I found this a nice change.
I worked this pattern before with Patons Kroy Sock variegated yarn in Cyan Stripes. Here's a pic - from January 2011. (The Gingerbread Lady herself commented on that post!)
In my blog picturing the previous hat I commented about the join. "One of the things I love about this pattern is the start of round. Rather than ch 3 and then work double crochets, the designer has you ch ONE, then work a dc in the same stitch." I want to add that I now use this method almost exclusively when I'm working in the round.
Great pattern! Well done!
