I found if I laid out each block it went easier and I kept a copy of the block next to my machine also to refer back to...
Example, after cutting all of the pieces, I laid out a block onto a 14" square of foam board ($1 a sheet at Dollar Tree) I divided the block into 9 sections like Rhonda showed. I would sew the segements of the block together and place them back where they belonged. Carry the whole thing to the ironing board, press and put them back in their places and back to the sewing machine... until the block was completed. You could stack several blocks/boards on top of each other and work on more than one block at a time.
