I decided to try top develop a hat using the "scarf" yarn that is so widely available these days.
I started with a basic bonnet pattern and decided to add the scarf yarn every 3rd stitch, but it wasn't quite the effect that I was looking for, so I finished it off plain after using the yarn for two inches.
The second I worked the scarf yarn in every other stitch, but only every third row. Still not what I wanted.
The final try I used the yarn every other stitch and every row. I am happy with this result.
After looking through my photos, I've found pictures of stuff I haven't posted here, ah well, never mind. Must remember to post when I upload photos to the pc in future.
