Thought Id give this a go and see how quick it really is, and it is!
For this I started with 5" squares.
|Turn and join ends mixing themup as you join|
|Flip over one end ontop of the next piece|
|again using your ruler measure from the fabric ede and cut at 2 1/2 ". Keep the odd piece you will need it for the last piece cut|
|keep flipping over and cutting (you are flipping over a 2 piece)|
|Hey presto a pile of four patches in no time .|
This can be done any size
