Questions about this pattern

Can I really use leftover scraps?

Yes — leftovers are knotted end to end into one scrap ball and crocheted straight through; the colour changes wherever they happen.

Is this US or UK crochet terminology?

US terms throughout (hdc is the main stitch), stated clearly at the start of the PDF.

Why work in the back loop only?

Back-loop hdc makes the soft horizontal ridges you see in the photos and keeps the fabric flexible.
