“k1, yo, k1″

First, knit a stitch.
Now the yarn over: you bring the yarn to the front of the work taking it over the *top* of the right hand needle. Then bring it to the back.
knit the next stitch.

You’ll have a “yo” the right tip–it’s sitting between the to knit stitches.

That’s the “yo” pure and simple. When knitting the next row, you treat this extra loop as a stitch! Notice, each “yo” will create a stitch.

In principle, I’ve answered your questions–the extra loop is on the right tip. When you come across it later, you just work it as though it’s a normal stitch. Usually, you will find the pattern has you knit or purl into that loop. However, it might tell you to do something different– whatever it tells you to do, treat the loop created as a yo as a stitch.

Here’s the problem: In almost any pattern containing a yo, you’ll find some sort of decreases *somewhere*. If you don’t find decreases, the number of stitches will increase, increase, increase until you have a zillion.

So, either on the row with the yarn overs or a later row, you’ll see “ssk”, “k2tog” “skp”, ” k3tog”, “p2tog” or *something*!

Notice in berry stitch, row 1, there is a p3tog in the row with the (K1, yo, k1) in same stitch instruction? The (k1,yo,k1) in same stitch turned 1 stitch into 3. The p3tog decreases 3 stitches to 1 and keeps the number of stitches from changing when you work that row. (If you stared with 16, you end with 16. Count the loops from the yo as stitches!)

Now on row 2, you’ll find you are purling into the yo!

Hope that helps!

Thanks again!
