Blink and you miss something at PYF. On Thursday evening, Celia Pym burst through the door in a whirlwind of joy and a little pink pansy in a pot. By the time I remembered to water the said plant on Saturday afternoon, our Rosemary had taught herself how to knit on 4 needles and made a very attractive pot in teracotta carpet yarn. 
How brilliant.
For a tough, weather proof, garden knit this spring, try carpet yarns in various shades of terracotta, only 40p/10g.
