I am in that sleeve stage, right about where I am trying to figure out if I ought to have decreased faster, or if I should just accept what is. There still is a good 5 or 6 inches to knit so plenty of time to decrease for sleeves. I worry anyway, just because I can. It's like running out of yarn, only about sleeves.
Seriously though, I ought to have done the math, but that would be too easy. There is nothing like living dangerously. Generally the fit is just right if I decrease slowly through the top half of the sleeve and then speed it up at the elbow. It usually fits about right if I decrease every 5th or 6th and then every 3rd or 4th if it is a worsted or dk weight yarn.
I did not get as much done as I had hoped too. I spent the morning with my accountant, and had lunch with my daughter in law and my grandkids before coming home. And then, I sat up late in the evening and knit and knit.
Today is rife with errands but before I do that, I intend to do the really important things. After a couple gray cool days, its bright and sunny. I mean to make the most of it and see coffee on the front porch playing a big part of my day!
