From the pattern website:

Though I have been a knitter since I was 16, I have avoided intarsia like the plague. This year, however, I decided to tackle an argyle sock. As I was knitting the first one and muttering under my breath the whole time, my husband saw it and said, wow, that would make a neat sweater, will you make me one? My immediate answer was a resounding no.

I plugged along on that argyle sock, having to rip and re-start it 3 times. I put it away for a while and swore that I wouldn’t make a pair. But being the perfectionist that I am I couldn’t said to have a knitting project sitting there unfinished. I started the second sock. This one was a lot easier and by the end I was actually having fun! So I re-visited my husband’s idea for a sweater.

He had the whole idea in his head and told me what he wanted: a fitted cardigan with large argyles and a retro flair. He picked out the colors too! So here is his Leisure sweater.
