I have a queen size that I am going to cut to use for the two baby quilts I am making. I have a front load washer/dryer combo (made for RVs) that has a delicate cycle. I cannot soak in it (that is what the directions on the package say to do). What soap and fabric softener do you use? I am not prewashing fabric because I think it is easier to cut and piece that way. JMHO
