Even though boucle yarn makes it difficult to see the stitches, this hat is worked in such as way that makes it very easy to follow.
I found an error on round 1, so please see the corrections on my blog HERE before making this hat. A section in parentheses was left off.

You may be like me and do not like working with boucle yarn. It seems like it would be difficult to work especially in the round with this hat. But it’s not as difficult as you may think. You do have to kind of feel the stitches, but it’s not hard to keep up with the number of stitches, because there is a space between each set of stitches that make up a pie shape. Just as the puff stitches do that with the purple newsboy cap (making it easy to count) that’s what the spaces do on the pink hat. You can’t see the spaces right now because when I was finished making it, I took yarn and wove it through the spaces, making a ridge as I was covering up the holes.

Many have asked about the belt shown. The instructions for the belt are not in the book, but they are listed on my blog HERE.
Please let me know if you have any questions.
