The theme for April Squares is ‘top‘, and we have five idioms, to choose from;

1. On Top of the World – summit, crown, peak (tiptop) or uppermost part of something.
2. Under the Big Top – topping or covering (or if you are really lucky a circus!)
3. Room at the Top – first or highest in position
4. Cherry on Top – something made even more wonderful by becoming square
5.  prefer to play around with word combinations such as top dog, top stitch, top hat, top secret, top knot, top drawer or top dollar!
