I have to say, I can do the thinking about being a grandma with no problem, but there is a lot of weirdness in calling one you remember so well as a baby a daddy! I digress. I am doing that a lot these days in the real world.
I am on ball 5 of the original skeins of yarn I had for the vest. As usual, I worried and figured out what I was going to do when I was short of yarn, and now I am not. There would be plenty there for button and sleeve bands. Of course, figuring how I was going to manage without enough yarn has left me with a vision and its a really nice vision. It's exactly the sort of vision and gives exactly the sort of feel and look that I wanted for this vest. I am not going to give it up now.
The plan calls for the 3 skeins of navy to go on the edges. Originally the plan was for simple 4 stitch cables, repeating a little element I had at the shoulders. That shoulder cable was just play so I don't feel bad about dropping it. I'm opting for simple easy ordinary. The blue will be simple stockinette. It means I will have to do a little shaping at the sleeve edges so they don't stand out stupidly, but I think I have that sorted in my head. Decreases in the curvy sections, none in the straighter parts should work.
I'm pretty sure I don't want to change to a ribbing or garter to finsioh the edges up with. That would just destroy the carefully planned look. I think this is going to mean that the blue parts are going to have to be a hem finished edge. Maybe I won't have any gray left over after all. Maybe I will have just enough.
