If you are having problems pearling after a row of knitting chances are you are knitting too tight. You should have just enough tension in your stiches so that they don't fall off the needles. Also if you tug gently on your work after each row or so it kind of orients the stiches the right way. I hope this helps :D
When we are little we cry because we have to nap. When we are older we cry because we can't nap. Live like an adult and dream like a child and leave life's little problems for another day.
