• dot one's I's and cross one's T's

• cross his path

• cross his mind

• at cross purposes

• get it across

• cross that bridge when we come to it

• put one across him

• cross swords

• cross the Rubicon

• a shot across the bow

• run across him

• the skull and crossbones

• put it across

• shot across the bow

• cross one's fingers

• have one's wires crossed

• across the board

• cross my heart
