OK this is what I understand so far. (1) pre wash is better for most of us? (2) If I do 10 sets, each set can have the same 50 fabrics as long as EACH set has 50 different fabrics? (3) Write name, and state on each baggie? (4) how many SETS does it table to actually make a quilt? yes I'm a green horn. (5) how many times a year do they have the 1.5" swap? Please someone help me? Thanks and have a blessed day.
