Increasing In the Back Hump of the Stitch

One of the most elegant ways to increase a Tunisian Crochet fabric is to insert the hook into the back hump of the horizontal threads and pick up a loop.(see video below).

Locate the forward vertical thread of the stitch in which you will perform the increase. It is indicated here with the knitting needle.

Tilt the fabric to see the spot where the vertical thread and the horizontal threads meet.

The bump running over the vertical thread is the back hump. Insert your hook here to pick up a loop when making an increase stitch.

Final appearance of increase stitches: the last 2 stitches made on the hook are back hump increase stitches.
