I did about 800 sq ft of Pavestone last year an a random pattern and my best friend was another pair of eyes (my wife).

Are you using all the same size pavers or do you have the different sizes ie. square rectangle and "twinkies" if so I ran out of the twinkies first completeing rows and ended up renting a saw to cut up some of the other sizes to complete the patterns ( I counld buy just individual pavers of that size)
