the originial pattern called for the blocks to sorted into DARK or LIGHT..... then assembled into alternating rows that created a greek key look... and honestly.. it started out that way... but after all the health issues and all the moves..... and other unsundry inturptions in my life..... things got mixed up.. and I wasn't sure which were light ands which were darks... so I descided to just destress and make it all hodge podged... I Like it better this way!....
