Just started knitting again after a few years and I'm having puckering in my stitches that I never had before.
I am knitting a Diagonal Check Pattern (or that's what it is supposed to be

):
P1, K4
P3, K2
, etc.
I think my problem is when I switch from P to K.........but I can't figure out what I'm doing wrong. I've attached a picture.......well, couldn't get picture to attach...message said it was too large, don't know how to change the size of a picture.........
