I use a flannel backed table cloth. I hang it on the wall and put my quilt squares on it.
I take one row off at a time then hang the sewn row up on the board again to recheck what I have done.
I like the idea of a picture because one times the blocks fall off.
I like the fact that I have to get up to get the next row. It gives me time to stretch out a bit.
I also use safety pins to signify the top and which row it is. I use one for the first two for the second and so on.
