jannxin, I would lay them out, take a picture for future reference in case they get mixed up. Then sew each block together to make a row, the when done, lay them down again and compare to the picture to make sure they are lined up the way you want and then start at the top and sew each row together. That's the way I do and believe me, taking the pictures not only helps if they get mixed up but also to have the extra eye to make sure you like what you've layed out. Hope this helps
