I found a fab online yarn store today, based back in my old homeland of North Kent.
They sell a wide range of budget yarns for the beginner and amigurumi fiend like myself, but also do have some more luxurious options should you feel indulgent.
Postage is only £1.99 per order as well, unless you spend over £15 and then it's free!!
Please check them out and put some business their way:
