Aaargh! Aaargh! Aaargh! I was so proud of myself for finally making progress with finishing the knitted sweater. I sewed up a shoulder seam, picked up stitches around the neck, knitted the neck band and cast off... And then I realised I'd done it wrong and had to frog it.
*beats head against desk*
At least I know how to do it properly now so should be able to finish it tomorrow.
