BEAUTIFUL cardigan! I have this pattern but have never knitted it. Seeing your's, I'm going to knit it too. I agree with the poster who said your's looks much better than the one on the pattern.
I often see this pattern on eBay, and its usually cheap - try UK eBay, which is where I buy a lot of patterns and yarn.
Here is an auction that is current, though it might be ended by the time anyone reads this.
The pattern is often labelled a TEDDY pattern, rather than KING COLE.
I love the idea of stitching in a label. Where do you get them? They do make it look very professional.
