So I went into the city this morning (after dealing with blood....sliced my finger open yesterday on a broken photo frame and it was apparently too early to take off the plaster...) and bought.....
The six smaller balls were three for £2, bargain. Poundshop wool is pretty good too. Larger ball was from a cheap bookshop, £1.49.
So for £5.49 I didn't do too badly.
I have already make loads of middle squares as well as other rounds of granny squares for the black edged granny square blanket. Photos tomorrow.
