Here's a picture of my blocked swatch. I was good and knit the swatch, but not really good to the extent of knitting a large, separate swatch of all the needle sizes I wanted to try.
Mainly, this is because I didn't like the size 3 needles (bottom part of swatch) right off the bat, so I didn't need to test bigger needles. I just knit the no-repeat part of the basketweave pattern until I felt I had enough fabric for a basic idea of the yarn/needle combination, then divided the same swatch into a new section with garter stitch and started in on the 2s.
I liked the 2s much better right off the bat (top part of swatch)-- and that is also when I realized that I was making the incorrect assumption about the left (right?) slanting decrease. (I always get the directions mixed up because as far as I am concerned, the top of the decrease is pointing in one direction and the bottom is pointing in another...Anyway, the decrease that is usually ssk.)
Obviously, Melanie used the sl1, k1, psso decrease for a very good reason, as you can see on the size-2 portion of my swatch, where the pattern is much more defined.
Even considering my flub on the size 3 portion, I still think that size 2 is a better needle for this yarn (Misti Alpaca lace). Any other thoughts/opinions?
