How To Yarn Over Twice

Im trying to follow a knitting pattern that mentions that we have to "weave in the ends? How is that done?
Here is the free pattern for the hood-Manta Manta Manta is woven diagonally. From a corner, stitches are increased, then decreased to make the opposite corner. Wrap the yarn over the needle creates a decorative edge on the blanket. Cast on 3 stitches. Row 1: Knit 2, yarn over needle (wrap yarn counterclockwise around needle, making a loop at the right hand needle) attached to the end of the row. Repeat row 1 until piece measures inches (51 cm) along one side. Next row: Knit 2, yarn over needle, knit next 2 stitches together twice, attached to the end of the row. Repeat the last row of up to 3 points remain. Bind off. 20 HOOD Cast 3 points and the same work to the straight edge of Hood Wrap is about 10 inches (25.5 cm). Knit 2 more rows, then bind off. FINISHING Sew Hood to a corner the blanket. Weave in ends. In the last step under finishing, it is mentioned about "weaving in the ends." How is it done? Thanks in advance community Answers knitting gurus!
Int Weaving the ends is a fancy way of saying "hide the tail of thread that are not shown." They often use the word "weave" as it passes the string on the existing points. Some people like to do this on the side of the work, others like it in the back of stitches, some like to hide inside a sewn seam, and others simply get in anywhere that is practical. If you sew the hood to the corner that has the tail attached to it, you can get the glue in the seam. That's my favorite method when possible.
