Cassandra (from Cambridge) and Josh (from Bedfordshire) both say to cut out the top right quarter of the square and put them on top.

Audre (from Singapore) says to "Split the square in half horizontally or vertically then join them''.

Arthur (from Cambridge) found a different way: "In the top right corner, cut a row of 3 joined to a row of 2 underneath. Flip it over and join it to the top''.

Are there more ways to do it??
