I'm with Brian. A thread or two off doesn't bother me. But if it really, really bothers you I suggest lots of pinning. Also, press the seams carefully and be sure that each intersection nests (so that the seams from one unit go in the opposite direction of the other unit, with no twisting).

Have been saving 4 inch, 3 1/2 inch, 3 inch and 2 1/2 inch squares for some time now. I take my left over pieces of material from my made quilts and cut them into what ever size squares the material allows. Right now I have only enough 4 inch squares to make a small quilt of mixed colors. I usually put a 2 1/2 inch inner border and 4 inch outer border. One of the problems I have had with these type squares is when sewn together in rows the corners do not always meet but off a tiny bit. So this time before sewing I went through every single square and made sure they were exactly 4 inches square. I know material will stretch while pressing, so will wait until the rows are all sewn together before doing that. If you can think of an easier way to do these type of quilts better please let me know. I am trying to be as careful sewing as I can.
