I don't know about the stitch count thing. Doesn't make sense to me, I think you end up with the same # of stitches no matter how you increase, as long as you still have the original stitch and the new stitch. Hmmmm... :thinking:
At any rate, I would refer you to this page: http://www.knittinghelp.com/knitting...s/increase.php
The one that I believe they were referring to on knitty gritty is the M1L increase.
