One of my first projects when I rediscovered knitting was a brief venture into crochet and granny squares. I got a load of Rowan DK wool from John Lewis, but really had no clue of exactly how much would be required and how long it would take to make a blanket. I crocheted like a demon (I thought) and made a disappointing little rectangle before I ran out of my main colour wool, got sick of weaving in all the ends, and gave up.
That was about 8 years ago.
Today, this little blanket failure found a purpose!
