Baktus Scarf

I am trying to do the Baktus Scarf. The pattern reads:

Cast on 5 stitches.

Knit to last stitch - yo - k1.

Row 2: K1, KTBL, K to end

Row 3: Knit

Row 4: Knit

It says I should have 7 stitches. How do I get 7. Is the KTBL really to mean knit 1 in front and back?

I’m not sure. There seems to be something wrong there. I understand there are several patterns out there for this scarf. Here is one that seems to make good sense. LINK

There’s a row missing or instructions somewhere - the YO in R 1 adds a stitch, but you’d need another one, probably at the beg of R 3 as well. Ktbl is just knit through the back loop to twist the stitch, it’s not an increase.
