Then you cut the blocks in half both ways so you have 4 equal sized square blocks.
(sorry forgot to take photos of this stage )
Then you rejoin the blocks.
In my case I wanted a random pattern so I just mixed them around.
I really like the effect.
This was just a trial with a pack of fat quarters to see if I liked the way it turned out.
As you can see it is not very big.
About 30 inches by 40 inches so I'll have to add some borders to it.
I think I'll turn it into a small tablecloth .
