I'm confused. Lesson three (outlined in the Crochet Assignment Sheets) tells us: The first st on the second row is worked into the first st; the last st is worked into the last hdc of the previous row, ignoring the turn ch (refer to Crochet Notebook).Repeat Row 2 only (increasing at both ends every row) until piece measures 5"wide. SO, I referred to the notebook and found only this: Increases can go anywhere and are made by placing two sts in the row below where you would usually make one st. Another option for
increasing in double crochet or taller stitches is to work into the first stitch, the st that is normally skipped.

Am I supposed to crochet a half double stitch into the turning chain at the end of the row, the beginning of the row, or both?
