PLEASE can anyone help?! I've been trying to felt charity shop jumpers - but they just won't shrink! I'm staying with friends in Leeds who've kindly lent me their washing machine for the purpose - but in spite of tumbling at the hottest temperature and spinning extremely fast - they refuse to do it! We tried the striped merino one - no luck! As you can see, my friend's now wearing it - it's perfect. Grrr! Then it was the extra-large blue lambswool one - surely this one would do it? Nope. If anything - it emerged from the wash even larger! I remember in the past putting my favourite wool top in the machine by mistake. It was ruined and fit for a five year old. Now I actually want the sweaters to go all thick and solid - it's just not happening. FAILED! Is there anything that will work?
