Crochet:Tturning when working double crochet

How do I get a straight piece?
Which is the first stitch to work into after you turned?
Which is the last stitch to work into?

In this DROPS Video we show an example on how to work double crochet (dc) back and fort with 5 sts.

Chain 1 st less than the number of dc you want (in our sample 5) + ch 3 additional stitches, i.e we chain 4+3 = 7.

Work a dc in 4th ch from hook, work dc in each of rem ch across, turn.

Ch 3 to turn with that replaces the first dc on next row, work a dc in 2nd, 3rd and 4th dc on row, and then 1 dc in 3rd ch from beginning of last row, turn.

Repeat last row for a straight piece with a constant number of stitches.
