Jenny's traffic cone tea cosy
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jenny brings in a knitted traffic cone-themed tea cosy she's had made, combining two very clichéd things that people wear on their heads. After she puts the item on her own head in the studio, Greg states that she looks like "quite a fun terrorist". He ultimately awards her second place.
