If you have trouble wrapping your head around counting and keeping track of your rows when knitting, click through to read this blog post now. It explains exactly how to count rows it for garter and stocking stitch, plus handy hints to help you keep track whilst you work!
How to make a nice edge stitch. At the beginning of the row, hold the yarn in front (instead of in the back as it usually would be). Insert your needle in the back of the first stitch (knitwise) and slip it (without knitting it). Continue knitting your row as usual. The last stitch is knit normally. Only the first stitch is treated differently. You can use this technique for stockiness or garter.
