A long, long time ago - way back in 1987! - I entered a knitwear design competition; I was lucky enough to get through to the final 12, invited up to Stationers' Hall in London for the do. Didn't win the overall, but had a great time, and the jumper I'd designed and knitted was professionally modelled on a catwalk, then appeared a few weeks later on Breakfast Time TV. No pattern, I designed it on the needles :)
I have no idea where it is now, I think they all got auctioned off for charity - if anyone knows, I'd be delighted to find out!
