The next thing to learn in your journey to becoming a knitter is the purl stitch. The purl stitch is the one that looks like a bunch of bumps or --'s. Together, the knit stitch and the purl stitch yield unlimited possibilities. These two stitches can be combined to make many different patterns, garments, and accessories. It really amazes me just how much these two stitches can do when they get together. As a previous post stated, these directions are in the Eastern European Style.
Here is a step by step guide to the purl stitch. The video is below. As with the knit stitch, you'll need a cast on row or a row of knit and/or purls. When referring to the needle with all of the stitches already on it, I'll call it the populated needle and the other needle will be referred to as the empty needle.
Step 1. Hold the needles with your cast on/knitted/purled stitches from your previous row in your left hand. The empty needle on your right hand.
Step 2. Stick the empty needle through the front of the stitch closest to the pointy end of the populated needle.
Step 3. Wrap the yarn around the empty needle, like you did with the knit stitch.
Step 4. Pull the yarn through the stitch on the populated needle.
Step 5. Slip the stitch from the populated needle off of the populated needle and drop it. Now you have a stitch on the empty needle.
Repeat these steps until all of your stitches are on the needle that was initially empty.
Turn your work and switch the needles like you did with the knit stitch. The needle with the stitches will now be in your left hand and the empty one will be in your right hand. Repeat until you feel comfortable with the purl stitch.
One thing to keep in mind. If you purl every row, you will end up with the garter stitch. If you alternate knit rows and purl rows you'll end up with the stockinette stitch.
