Tiny Tuesday - Mystery Macro.

I've started, so I'll continue. Today's "Tiny Tuesday" theme is as in the title.
In the unlikely event that this end is too difficult to identify, the other end is shown in the extra and might give a clue. If even that fails, all will be revealed in tomorrow's extra.

If it hadn’t been for today’s challenge I would have been stuck.

I seem to be stuck in the rut of posting two pictures on alternating days and have just done yesterday's, "The Hedge."
