The yarn I'm using was a recent buy from budget supermarket Aldi. It was only £3.99 for 4 x 50g balls which is a bargain by any means. I thought the quality may not be superb (they do say you get what you pay for, dont they?) but it's knitting up fine. I chose the black/grey colourway for baby bro in the hope that they will actually be worn.
Now just to get the second sock done (sigh!)
