As you can see this is going to take a while to set up. It starts with knitted squares that are joined and then more are added. There will be six rows before the main body of the vest is knit. That should go much faster. There will me a multitude of ends to work in too. [sigh]It is a bit of a challenge, but that is what keeps the gray matter young, no? Knit on size 6 needles and my gauge was spot on so I think the Trekking will work out well.
