This week I started and finished an adults hat made with Stylecraft Chunky Harlequin, and a baby's waistcoat from the same yarn. In total, I used 2 balls. Last week I started a hat in Ice Yarn, making a ribbed hat. This took me a while because it was US sc in back loops only, so I had to concentrate to just do one loop. If I was to do it again, I would do US dc so that it goes a bit faster!
I put the waistcoat on a teddy to model it, the yarn is hard to photograph!
The purple one matches the baby hat I made our little girl.
