Don't read any further unless you want some help solving this puzzle!

Hint #1: This puzzle uses 12 planks and the solution has 3 squares.  Since squares have 4 sides, this means the 3 squares should each use exactly 4 planks.  (Because 4 + 4 + 4 = 12)

In other words, no 2 squares will share a plank.  Also, each square will be the same size.

Hint #2: Although no 2 squares will share a side, the corners will still touch.

Hint #3: There is more than one way to solve this puzzle, but try moving the 3 planks on the far right that make a sort of "C" shape.
