To create a bar increase knitwise you are goig to place the right needle into the front of the stitch and knit it.
Leave the stitch on the left needle!
With the new stitch on the left needle insert the right needle into the back of the stitch you just knitted and knit that stitch.
Next slip the 2 new stitches off of the left needle to the right needle.
you can tell where you made the increase because it leaves a bar behind.
