The psso in the So-Called seemed very easy--maybe because I used large needles.
There is one tip I learned, though, that worked out very, very well.
The directions tell you to psso, but before dropping it off the needle to knit into the back of it. Sounds confusing. I read a tip on this, followed it and you get the same results--do a yo before psso. Pass the slipped stitch over the knt and the yo. The results are exactly the same, but it seems just so much easier to keep the pattern flowing.
So it's sl1, k1, yo, psso the knit and the yo.
