That pattern is a very simple drop shadow design. Make the squares the size that you want and change the other dimensions (shadows and spaces) to something that works well for cutting and piecing. You can leave them the same as they are in the pattern or make them a bit bigger. The shadow effect will change only in the appearance of the height the squares are floating (actually it's the angle of the light source, but that gets into perspective :roll: ). The wider the shadows, the higher they float. Draw it out on graph paper and color it to get an idea of what looks good to you. Don't make it harder than it is!
