Getting those bricks sorted by size really does make all the difference. I've had to do this before with old pavers from a demo project. It's a pain, I mean, but grouping them lets you see what you have to work with. If you don't sort, you end up with gaps and uneven lines that look messy. Lay them out in piles first, then start from one corner and build out. Takes time, but the path comes together solid and straight in the end.
