This is a really simple pattern, based on a 2 row repeat. The pattern uses the half-treble crochet (this is in UK terms, in US this is the half-double crochet stitch) worked in groups of 2 (htr clusters) and is a variation of the traditional Granny Stripe, which is usually worked in groups of three treble crochet stitches.

Worked in stripes.
Simple but effective border edging.

Pattern easily adapted to bigger or smaller sizes.
