The adult hat I made from sea breeze blue roving yarn and blue bamboospun yarn (doubled up). I used the adult hat size round loom. I casted on with the crochet method so the brim would be a little tighter. Also, this had I made for my friend Nancy in Nashville for her sister who is starting chemo soon.
Then this smaller children’s hat (may be small enough to be a baby’s hat) I made from just the blue roving yarn. I did something different with the brim in that I did a pattern of knit one purl two and it turned out pretty good for a first time experiment!
