Marymo - if you get finished with step 2 that will post on Saturday and decide you want to make the biggger size, you will be able to do so before you go on to step 3. You will just need the additional A and B fabrics and some more of the 2-1/2 x 4-1/2 pieces.
I just knew Sunlite would come to urgodschild's rescue and provide a snack as well. Alway helpful.
