Rainbow Scarf Cats. Well, here are the results! It took quite a bit of trial and error to get the hat looking like a hat, and not just a piece of clay stuck on top!
In the end, for the small yellow cat, I used the santa hat template (essentially half a circle rolled into a cone), and then rolled up the eges to form the woolly rim, and cut off the point to flatten it. Having the ears poking through the hat completes the look.
For the tall cat, I cut out a full circle from thin clay and then smoothed it down to form a dome, I added a thin strip of matching clay around the rim, and indented it to look like a ribbed hat. The fact that the hat covers his eyes was a happy accident!
