(k1,k1 tbl) INTO THE 2 YO STS
On the prevous row you must have made a double YO (yo twice). So on this row, knit into the first loop, then on the 2nd one, knit it through the back loop to twist it.
I still dont get it. how do you twist it.
The st gets twisted when you knit through the back leg. A stitch has two legs, one hangs over the front of the needle and is usually closest to the tip and the one you generally knit into. The other leg is over the back of the needle and when you knit into it, that will twist the st. On the Glossary page there’s a video for ktbl, take a look at that.
