I made this small table runner using ice batik yarn (dk weight) and 4.5 mm crochet hook. The pattern is called as 'neat ripple' (by Lucy, attic24). I chained 45 and followed the pattern till I reached the desired lenght. You can easily change the size of the table runner. Just chain multiple of 14 and then add 3 more chains (14x+3). Eg. Ch 31, 45, 59, 73, 87... And follow the pattern till you reach the desired lenght.
