I like to finish one top first but while taking a break from quilting, I make other squares for other tops so that when I am done with one, I can go right on to the next one and get it sewn together. I have a bunch of crazy squares made, some pineapple squares, some pinwheel squares started and some dresdgen plate squares started. that way, I alway have another quilt ready to be put together when I am done.
