A long clip-in ponytail extension that fades from black at the top into loose burgundy curls at the ends, and a cartoon green alligator strolling along on two legs and waving hello.

Wave among the frames and backgrounds
Rectangle, Square and Circle Frame give a shape to fill, Gradient and Texture give a surface, Divider separates blocks of text. Wave gathers anything built on a curving line — wavy edges, flowing shapes, and, by a quirk of the word, a wave of the hand.
The ponytail
Photographed straight on, with the clip visible at the top and every curl sharp at the edge. It suits a hair salon price list, an online shop for extensions or a before-and-after post about ombre colouring.
The waving alligator
Big blue eyes, toothy grin and a friendly pose make it a greeting character. Put it on a welcome sign for a kids’ class, a zoo event flyer or a “Hello” sticker set.
